Some kind of low poly grass is probably your A reference, referencing your B being the character
A->B
that or you have your player character in a very strange spot lol
failing all of literally everything people have said so far you’ll have to re-create the player character
^ im not sure why the formatting goes away on that but it’s alot easier to read the steps if you open it
Hopefully you didn’t force delete something that’s quite some trouble to fix, that i still haven’t learned, the engine has pointers that never got removed or updated properly meaning you’ll have to understand c++ and callstack errors or copy paste everything you’ve done into a new character bp that is not a child of ThirdPersonCharacter
