Project crashes every time on launch

Development Platform & Builds

I was on 4.17.1 I think when it happened. Tried upgrading to 4.17.2 and it’s still happening. It first crashed in the middle of compiling through Xcode - and now won’t reopen. I’m mostly working with Wwise audio code.

Crash Report:

To be clear, it’s happening loading the project from the launcher. It can’t even open the project fully.

3

try to verify the engine in launcher

4

For me 4.17 doesn’t even start on mac even without any project
since launcher deletes shader files for some reason :))

5

Tried to verify and it didn’t find anything. Still has the same problem on launch. It’s weird that it was working for weeks up until this point.

6

Still the same issue :frowning:

7

Them verify it again, close the launcher and lunch the editor app directly feom the instalation location

Hmm, I had this issue before… then I just tried renaming the “Saved” folder in explorer to “Saved.OLD” and do the same for “Intermediate” folder and reopen the project… It worked for me…

I recompiled the C++ project through Xcode separately and now Unreal launches fine. Very weird, but I think I’m good now. Thanks to those who responded!
