After I first experienced the crash, I downgraded to Ardour-5.11, now I just
installed 5.12 again to produce the backtrace, and interestingly its gets a
bit further this time. The application starts and opens the dialog which lets
me choose one of the recently open sessions. However, immediately after
selecting one, it crashes again. The backtrace is attached, I hope it contains
all the information you need.
Kind regards,
Markus
