[Daniel van Vugt (vanvugt)]

Thanks for the bug report.

This is most likely to be bug 1958191 which for most people was fixed in kernel 5.15.0-40. So please update your system:

  sudo apt update
  sudo apt full-upgrade

and then reboot. If that doesn't fix it then please try adding kernel parameter:

  intel_iommu=igfx_off
