Should also mention that even if you press z whilst knife cutting it wont cut through

Mesh in bureport file can be cutted in Perspective View.
Any info on how did you create the mesh ?

I did not manage to reproduce bug from scratch

Note that knife tool has some issues at extreme scales, and this object is around 400 units on each side.

This is likely a problem with ortho ray casting which can be resolved.
