Summary

For the last weeks my UEFN crashes when i press launch session, it crashes when connected to my ps5 and also when not connected to anything. It started happening since i imported assets from unrealengine and materials from internet but when it crashes it does not show what the issue is in the crash log, atleast i cant find it.

it also happens when pressing publisch project, it happens when loading bar just started and the description of the loadingbar is ends with: API

Please contact me if something is not clear or if more information is needed, ive worked on this map for a year and dont want to lose it.

Steps to Reproduce

Open map> Yacht
Press Launch session(with or without a connection wont matter for me)

Expected Result

starts loading and something would happen on ps5 to connect so i can play in the map on ps5 with live edit from UEFN

Observed Result

UEFN closes immediately and then shows the crash log

When pressing publisch project it didnt close as fast and started loading first, but it crashed at its first loading step, description ended with API

Platform(s)

windows, ps5

Additional Notes

happened after downloading assets from unreal engine(not FAB) and materials from internet. but i dont know if it was working before the downloads, it was at one point but i didnt use launch session for a very long time. before importing those assets
