Edit I found the game also crashes when build as a standalone exe too.
I got this error and crash when running -game for standalone test on editor.
Assertion failed: (Out.ModuloMasks.X + 1) == Out.Dimensions.X &&(Out.ModuloMasks.Y + 1) == Out.Dimensions.Y &&(Out.ModuloMasks.Z + 1) == Out.Dimensions.Z
Which is wierd because my other project which are almost identicle, has no problem.
This only happens after migrating my projects to 5.5.
I mod the ue engine to prevent the modular crashing, but now it seems to crash else where. Now that I think of it, it probably caused by earlier tread giving it bad parameters, so fixing this won’t help.
I can play stanalone from the editor though, just can’t use -game stanalone launch with this project which is my main project.
I probably the only one with this problem, so I guess I’m on my own rofl.
I finally found the issue. It seems that pak system in UE 5.5 is completely broken.
I could compile and package the game fine. But when the I launch the standalone shipping version, it report that bunch (probably all) assets are missing and crashes.
That’s so strange. I have a similar issue, but it’s a GPU related crash.
Only crashing on 5.5.1. standalone build - identical project runs fine on 5.4
