Short description of error
Knife tool often creates double geometry in cut areas. Sometimes doesn't even finish the cut properly. When you zoom in during cutting and move cursor out of the model it moves the cut point to 0,0,0 location.

Exact steps for others to reproduce the error
I think everything is in the video.

Indeed, Knife tool seems to perform worse with extreme wide angle view points, as in your file. Unsure how to triage.

I have the same problem.
"during cutting and move cursor out of the model it moves the cut point to 0,0,0 location."

I can too reproduce this if I zoom in during cutting with that file.
