UE5.0.1 totally break packaging, without any error : compile process stuck

Hello,

I need a bit of help cause for the moment, i’m clueless and afraid to have loss a two years old project (got some save, but…)

The issue : When i try to package, the compiler stuck on a file, it’s always the same step number (99/101) no matter the file. Without bUseUnity option, it’s stuck to, at the step 8/10.

Compiler : VS2022.

If i let the compiler run, it finish ending some hours later by a out of memory, and i know it’s anormal cause this compiling phase is usually really, really fast.

I already try : commenting files (it just go to another file, and stuck at 99/100), fixing warning (without any success), deleting intermediate build and saved folders.

If someone have an idea, i would really love to know, cause i’m a bit deseperate.
If you need anything to help me, don’t hesitate.

Fixed : just fully re-instal UE5.0.1

Visibly, upgrade from UE5.0 to UE5.0.1 break something, i’m not alone in this case.
So just clean install UE5.0.1 if you are in this situation.
