Knife Tool seems to be broken. I only get Error messages when i want to use it

Confirming, it is broken in Blender 3.1

Error: Python: Traceback (most recent call last):

Probably not a real fix, but this worked for me:
In QMeshOperators.py change line 386
from
return bmesh.utils.face_split( face , v0 , v1 , coords , use_exist )
to
return bmesh.utils.face_split( face , v0 , v1 )

This made cutting functional again for me with no errors. I never used this tool until recently so I can't compare it to it's intended behavior, but it seems to be working as I'd expect.

Tried suggested change to QMeshOperator.py line 386 but it didn't work for me. Maybe you changed also something else maybe.
Just hoping to find a solution for this Knife functionality problem.
