[Bug 2146477] [NEW] 26.04 amd64 snapshot 4 "ModuleNotFoundError: No module named 'cutin.vendor'"

Public bug reported:

The installer boots up to a point where it continuously cycles every few
seconds between a screen that just says "Ubuntu Resolute Raccoon
(development branch) ubuntu-server tty1" and the python backtrace in the
screenshot. The backtrace blips by fast enough that I was only able to
see it by capturing it on video and scrubbing it frame by frame.

What I did:
I downloaded the 26.04 snapshot4 amd64 iso
I put it on a ventoy usb stick
I booted the image on an amd64 pc (dell t5500)

** Affects: linux (Ubuntu)
Importance: Undecided
Status: New
