Crash on launch

Everytime i start UE without launcher it crash. (from Epic Launcher work) 4.7.3 / 4.7.4

Its work before. (at least with 4.7.3)

not bug report. i got thit error.

Unhandled exception at 0x00007FFA6C7EAEC2 (UE4Editor-CoreUObject.dll) in UE4Editor.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.

Hi knack,

Where are you starting editor? Is it editor .exe, or are you opening a .uproject file? Do a quick Verify install in Launcher. Then, if you’re still having problem, please and attach your crash log. If it’s editor.exe that’s crashing, you can find that in Engine\Saved\Logs\ . For a project, it’ll be in your project folder ProjectName\Saved\Logs\ . Thanks!

After crash, did you submit call stack to Epic? We weren’t able to find it. Next time it crashes like this, please include a description and select Send. Thanks!

open uproject work, only crash on direct access. (shortcut in english i think)

Link to:
“C:\Program Files\Epic Games\4.7\Engine\Binaries\Win64\UE4Editor.exe”
No logs. In “Saved” only “UnrealBuildtool” directory.

No call stack, when i click in shorcut and editor reach 98% windows popup a dialog box with “Unreal engine stop working” debug or Close program.

If i click in debug show that previous error i posted-

ok i got a crash report today. I submit… This launcher from Launcher. I can’t start Unreal without select a project.

Unknown exception - code 00000001 (first/second chance not available)

Okay, I’m a little confused. Does this crash occur when using Launcher, or when running executable? If it’s from Launcher, try going to Library page in Launcher, select 4.7.4 engine slot, and choose Verify from drop down menu.

I didn’t see your crash in our database. Can you try again, copy information and paste it here, and make sure you hit Send? Thanks!

Crash occurs if a launch editor from a shorcut (without use launcher)
or from launcher, selecting 4.7.4 slot.

First case never give a crash dump (just Unreal stop working)
Second case sometimes give me a crash dump, not today (i will post if got one)

I add a video. Rename to AVI.

I verified installation.

if i start a uproject or select a project start ok. Seems only occurs when start without project.

Okay, I’d like you to try removing configs for editor for us. Go to \Engine\ folder ( C:\Program Files\Unreal Engine\4.7\Engine by default) and copy Config folder to desktop, then delete original from Engine folder. Then try opening editor through Launcher.

If editor launches without issue, please and attach that entire folder ( ones saved to desktop) to this post so we can take a look at what might have caused problem. Thanks!

That not work. If i delete that directory or ini files only, all stop working (open a project and launch editor without project)

suppose autogenerate configs? because seems no.

When restore move config files to his place after try i got a crash report

And a bug report (i submit) and attach
I attach to config files.

Config.rar.txt (config files rar)
Bug(2) - Crash report after delete all config files.
BugOrig- After restore config files again

Okay, can you check \Engine\Saved\Logs\ now and /attach anything you find in there?

I do another test, i delete INI files, and i click on verify, that restore ini files but without luck, crash still there.

Okay, one more place to check. Go to C:\Users\YOURUSERNAME\AppData\Local\UnrealEngine\4.7\Saved\

AppData folder is hidden by default, so you may need to either expose it or go directly there by using path above (with your user name).

There, move Config folder to desktop as before, and try again. You can get logs, too, while you’re in there; and attach that Logs folder and Config folder.

Not luck deleting that config directory.

Hey knack,

Thanks for these logs! This should give developers something to work with. I’ve created a bug report for this crash (UE-13276) and included information you’ve provided, and I’ll let you know as soon as I see an update. Thanks for your patience!

Hey knack,

developers would like to get ahold of your engine folder so they can take a look. Can you up 4.7 folder ( C:\Program Files\Epic Games\4.7 ) and upload that somewhere like Google Drive or Dropbox (both are free), and give us download link? Thanks!

uff I have a slow upload connection (25kb/s) and that are 12GB, that will take me ages.

Anyway i want solve that problem, i will investigate other things before upload.

i rename 4.7 directory and download again 4.7 and still not work. its really relevant upload that?

Since i check files, i think all config files too, i will look later today at windows register.

Hi there after looking at your logs can you try deleting CachedAssetRegistry.bin from \Engine\Intermediate\ in your engine install directory?

After that try launching editor.

thanks but that file not exist, only Build and UAT directorys in that location.

Hey Matt that solve problem, but i found CachedAssetRegistry in %appdata%/local not in engine install directory.

finally SOLVED. Thanks guys.

Cool, yeah sorry I am glad you found it though.
