UE5 Editor loses connection to parent class when reopened

So this seems to be a bug.
I have a CPP Class compiling just fine. I create a BP Child class from it. Testing BP in Scene everything works fine.

I save my progress and reopen the Editor. Now my CPP files do not appear anymore and the BP has a null parent class. Recompiling shows my CPP in Editor, but connection remains broken. I cannot re-assign my parent C+± class in BP because it doesn’t show. I have to reconstruct the whole BP, but as said, it won’t survive closing the Editor.
UE5.0.3

Any fixes? Thx.

Hey, I just deleted the “Binaries” folder in the project and opened the Editor. That worked and reopen didn’t take long. No Shader recompile. Just asked me to rebuild the project, which was fast.

Question is, will you have to do that every time you remove/rename/move an Asset? Or is it only related to Cpp- Files or BPs?

This bug is still in 5.2.0 and the given solution (i.e. delete Binaries directory) works there too.
