Fatal Error "and" FName Overflow - Unreal Engine 5.5.4 - Convai v 3.5.0

I am having a problem in my executable that occurs from time to time but always at the moment of starting the conversation the application crashes. This is the summary error:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000000000000000098.


Convai::FConvaiEditorModule::ShutdownModule()


My second problem is FName Overflow:

FName overflow, allocated 1024MB of string data. FName strings are never freed and should be created sparingly. Some system might be generating too many FNames, see call stack.

Before when I was with unreal 5.4 version I didn’t have these problems but lately I’m having these problems but I don’t know whether to continue with UE5.5 or go back to UE5.4 as this would bring me problems of redoing many things for the previous version.

I hope you can help me,
Thank you.
