The Bad Cast and Error GM appeared only when I deleted GM before start UE, cause in opposite case UE will crash. And this Bad Cast error solve the problem with crashing cause when I reset node and cast become normal UE start crashing

If I somehow can help you with exploring this issue by sharing files, just tell me and I will share it with you

Oh I see, you removed the class externally so it didnā€™t crash. Iā€™m still uncertain why your pawn canā€™t cast to the GM at all, I canā€™t replicate it on my end but it does still seem like a bug despite that.

Unfortunately due to policies I canā€™t download project files. I would report it with as much information as you can, just to be safe:

ue5 Is SUPER BUGGY!
Exactly the same When I build the following circular reference (MyHero MyPlayerController MyMode MyHero), I have the same problem as you, and the 5.4 version has no such problem.
Some days ago i found IK redirection behavior of version 5.4 is inconsistent with the editor after packaging-the characters hands and legs seems to have their own thoughts. To solve this bug, upgrade to version 5.6, and more bugs appear

I have this exact issue with my project with this callstack whenever I try to launch the editor:


Assertion failed: !Object->HasAnyFlags(RF_NeedLoad | RF_NeedInitialization) [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\Serialization\AsyncLoading2.cpp] [Line: 10517]

I was able to fix it once by reverting the BP to an earlier version, but after remaking the changes it started to happen again. I didnā€™t even have any errors or anything in them. Iā€™ll try deleting the file and recreating it entirely, but any help on how to fix this issue will be great.
