Crash opening a project in 4.7.3

Development Programming & Scripting
1

I have this project that I’m using for stuff I would like to submit to the marketplace. Unfortunately UE is crashing when I’m trying to open the project with 4.7.3. I’m sure it worked with older 4.7 (though I’m not 100% sure about 4.7.1 or 4.7.2).

Only not so typical thing I can think of that I have done, was when I was opening the project a few days ago (which was probably in 4.7.2) and dialogue popped up, it was either auto-import or auto-reimport of assets which had to be animations and I canceled the dialogue, then closed the project. Few days later, 4.7.3 is crashing with the following errors:

No idea if the canceled dialogue through some bug could cause this or if this is some problem introduced in 4.7.3.
I would really appreciate any ideas about what I could try or should do the next.

Thanks

I managed to work around the problem by manually moving the character folder that I was suspecting is “problematic” somehow out of the project folder structure. Opened the project, got some expected errors and warnings from the missing stuff, then saved and closed the project. I moved the character folder back, started up the project and got auto-import/reimport dialogue again and all seems to be working fine now.

Hey ,

Glad you managed to find a fix for the issue. I will make sure that if others begin experiencing a problem similar to yours, I suggest the workaround you used to fix the issue.

Thank you,
