Hi decod-fp,

This appears to be a crash which we have a report for (UE-23119) but no reliable reproduction for. Would you be willing to and upload project somewhere, and send me a download link? You can do so privately via forums, if you prefer:

Thanks!

Hey !

Hum, I’ll try to upload project, but it’s very big project ( 35 Go… because it’s not an optimised game…it’s a fat architecture visualisation :confused: )

I’ll upload this night.

But, I can say this :

I tried to open an old version of backup project. No problem at launch, no crash.
I copy/past a different part of content, one by one. Maps : it’s ok

But, when I replace material folder, or mesh folder >>> same error

Please let me know when you have, thanks.

After that, I’d like you to try removing Intermediate folder from project, and then opening it. Please make sure that you keep Intermediate folder there when you it to send to us (so we can get a reproduction case and hopefully stop crash from occurring again). Let me know what happens.

I tried to delete Intermediate / Saved and DCC folder

When I try to open my project, Unreal build a new Intermediate and Saved folder, but it doesn’t work :confused:

You have a new MP, with my project ( link ) !

Thank,

, do you have received my project ?

Hi ,

I got project this afternoon. It may take some time to go through it, but I will keep you up to date. Thanks!

Hi ,

Thanks again for project. I can confirm that this crashes on load for me, and it appears to be same crash we already have in our system (UE-23119). I’ve updated report with link you gave me for project, and made devs aware. Hopefully with this devs will be closer to finding a solution for you.

In meantime, my understanding is this happened after you crashed while attempting to save assets when you didn’t have enough space on hard drive. This may have half-saved some assets, which might be cause of current crash. In that case, you may need to start removing assets from project to see what’s causing problem, starting with .umap. You should have some backups in your project from before that HD space crash, so you might be able to replace them.

I had this exact same problem and based on this answer I was able to narrow down exact corrupted asset that caused issue (it was pretty easy because it was new one I just created and that was saving when crash occurred.)

i find this problem when i open new project.then i look size of my space,it is zero byte .i delete some files ,then create then projects again,it is fine.
