Thanks for your help. Obviously this seems to be the reason for the bug. I blacklisted the ucsi_acpi module and the system boots correctly. Hopefully there will be a backport for the 5.15. kernel so that I can remove the blacklist. Otherwise I have to wait for an Ubuntu distro with 5.16. kernel.
Again thanks for your effort.
