4.14 Crash the moment I access the "Details" tab

I’ve worked hard on this project. Now, whenever I access the “Details” tab of anything, the Editor AND the Launcher crashes, if it does not entirely freeze my computer forcing a manual reboot.

I can access the “details” of anything in the TTP template, in another new project. It only crashes when I do something in the project I’m working on. As far as I know, I changed nothing in my environment. As one point the Editor asked me to rebuild the blueprint references, which crashed, but I could still work on my project after that.

It works as long as I don’t interact with the “Details” of anything. I can drag new assets to the level, use the arrows to move them, but if I only pass my mouse over the details on something that would summon a tooltip, or click on a coordinate location or rotation, or click on the texture to change it, the editor freeze, then crashes, along with the launcher.

Anyone with idea so I don’t lose everything I’ve done so far?

Is there a way to manually tell the Editor to re-reference my blueprints (or whatever that was) to see if it could be that?

I finally could paste the clipboard after the crash, which I was not able to do before.

Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0006 - ‘HUNG’)

I could edit the details of a widget (my HUD). But still not when I want to change the position, or texture of an object (simple cylinder) in my level.

It seems to be this error. Unreal Engine Issues and Bug Tracker (UE-40807)

Although for me, it doesn’t seem to happen when I play with objects with reflective maps, but when I try to change a texture on anything. I just edited the location details of a blueprint without texture (no object, just a blueprint actor), but when I clicked on my new simple cylinder, and went to the details tab, everything crashed.

If anyone has a solution, even temporary, I’m adding on the 300+ users who have this bug.

Hi Maha Vajra,

We have several GPU crashes logged that are all related.

There is a possible workaround that we are investigating. The GPU crash may be related to microsoft’s Timeout Detection & Recovery(TDR) feature. You can find out more about it here: Timeout detection and recovery (TDR) - Windows drivers | Microsoft Learn

Basically, it detects if your GPU is hung up and if it passes a certain amount of time Windows will automatically reset the GPU resulting in the crash. This is done to prevent a freeze forcing a hard reboot of the system.

Sometimes you need to add a little more time for your GPU to process before Windows causes the reset. To do this you need to change the TDR delay.

I have two suggestion on how to do this you can do it manually yourself OR you can download a tool that will do it for you. However, I haven’t used the tool that much myself but it does appear to work. (Use at your own risk)

Method 1 (manually):

  • Go to the this link:
    Testing and debugging TDR during driver development - Windows drivers | Microsoft Learn

  • There you will find a section called TdrDelay it gives you all the information you need to create a registry key that will change the delay time

  • To open your registry open your start menu and type “run” once the window is open type “regedit” and hit OK

  • Now you should have Registry Editor open this is where you will use the info at the website I just linked.

  • First navigate the key path HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers

  • Right click on GraphicsDrivers and go to new> DWORD (32 bit) value

  • You will see a new key appear make sure to name it “TdrDelay”

  • Right click it and select “modify”

  • Under Value data enter 10 (this is the number of seconds to delay) make sure you have Decimal selected as the base

  • Hit okay and restart your system

Method 2

P.S. Be sure to let me know if this helps your crash!

NOPE! I set my TDR to 20 seconds (10, 12, 16 were not enough to get me working), and I wait 20 seconds when the editor seems loaded (give it time to finish addressing disk), before I do anything. Then, I play the level, forcing the editor to load a few things (that part works fine). I placed my Details tab on the far right of my second screen, so I can work via the other windows, without hovering above the Details window. (I can change stuff in the Details when there are no material selection, only variables and properties).

Then, I can work for around 10-15 minutes before a crash, if I don’t address anything that has to do with changing a texture; because the moment I click, or get close to the "Material "pull-down menu in the Details tab, now I just have to wait 20 seconds instead, before the D3D Hung crash. So far, I save often, and can’t work on the levels themselves, nor the meshes. I’m just building blueprints hoping a solution will happen, hoping I didn’t lose 1000$ of assets in the UE marketplace, and loads of hours of work.

My CPU is an Intel iCore7 X990, 6 cores (12 threads) at 3.47Ghz. 16gig of high-speed ram. Main disk is 500gig SSID disk for quick boot. Project is on my work disks: an array of 4 x 2TB disks (Total 8Terabyte) in Raid 1 for quick delivery. My graphic card is a Geforce GTX 570, which seems to be the root of the problem. Otherwise my machine is a monster.

Any other solution? I’m willing to work with you guys and try stuff.

Okay, thank you for the feedback. We are still investigating this issue. I will update this post once more information is found.

[EDIT] A user (IronicParadox) suggested that going into the content browser pane > click the little eye that says “View Options” and uncheck “Real-Time Thumbnails.” made the engine much more stable.

Could you let me know if this helps?

Thank you for your patience.

Unchecking “Real-Time Thumbnails” resolved the problem (4.15). !

Unchecking the Real-Time Thumbnails resolved also my issue(4.15). !

I have exactly the same issue with 4.15.1 and the “Unchecking the Real-Time Thumbnails resolved also my issue(4.15)” resolved my issue also.
Hope to get this fixed in the new released of the engine.
