engine crash on startup even after deleting error file

i a have a class called USpellHandler, it is the class that causing the error, first i got the error on the constructor so i commented everythin, even still the error didn’t fix, i even removed the file .h and .cpp and rebuild the project successfully but still i get the same error one USpellHandler even though it’s removed.
I tried deleting intermediate and regenerating program files, but id didn’t fix it.
this is the crash log :

i opened the project from the visual studio by clicking start debugging and it opened , but when i open it from the ue4 launcher and select project it crashes, why ? :slight_smile:

Greetings @AkashiSama009

Welcome to the Unreal Engine Community Forum! With the USpellHandler files that you deleted, did you remove them from UE as well as from the folder? I’d start by ensuring it was removed from both. I hope this helps!

how to remove it from ue ? its a c++ file
