Hi, I had the same problem and this worked for me.
Have you tried it?
#729

Can confirm it works, but won't close the issue since no fixes has been pushed to the main branch

Same error here.

How did this error end up in the main branch?..

Epic hasn't made any updates to this since blender 3.6 and looks like probably wont maintain the project anymore, so we created a fork here:
https://github.com/poly-hammer/BlenderTools

This new release supports blender 4.1.
