About the installation: Ubuntu 20.04 - Clean installation with this options:

  • Minimal installation
  • Custom partitions
  • Download updates while installing
  • Install third-party software
  • Wayland session

I've also tried reinstalling with different ISO without luck. It appears about one or five minutes after login in. The updates are up to date.
