It seems that pyright does not like the mismatch between __init__ and __new__ in sub-classes of BaseException. I'm not sure what to do about that, to be honest. Considering that BaseException_new just ignores keyword arguments, we could try adding a kwds: Unused argument to BaseException.__new__.

That seems to reduce the amount of errors but a lot of them still remain (I pushed the change so that you can see for yourself)

I'm a bit unsure how to proceed here. The stubs now seem to match the implementation. I'm not sure why pyright complains.

I'm as stumped as you are 😅
