this is in a packaged project made with the binary version of the engine (4.26.1) . I haven’t changed any rendering code ect. any help would be great. iv attached the log but i’m assuming this is the meat of the problem:
=== Critical error: ===

EDIT:
this appear to have been caused by a UArrowComponent that was set bIsEdiorOnly = false or HideInGame = false. don’t know why but I isolated it down to that after 2 days. I need to get better at debugging
