ArdourGUI hangs on startup with 100% CPU

I just installed the version 6.9 which is available from the Ubuntu repositories.
When starting it on the command line it will hang with ArdourGUI showing around 100% in the “top” command.
I have Ubuntu 22.04.1 LTS with Budgie desktop (german).

The terminal output is
Ardour6.9.0~ds0 (kompiliert mit Version 6.9.0~ds0-1build1 und GCC Version 11.2.0)

now it hangs
Should it run on this Ubuntu version with Budgie desktop?

We cannot provide official support for Linux distribution builds here.

Perhaps another Ubuntu user can help you out, or you can try the free/demo version from Download Ardour | Ardour Community (if that has problems, we will help; the current version is 7.2)

Thank you for your advice, the demo version has started successfully.
I will continue trying it out…
