Ardour 6.9 crashing on exit

I’m currently on Manjaro KDE.

Sometime after Ardour 6.9-4 was replaced by 6.9-5 in the repository, the program consistently crashes on exit. At the time of 6.9-4 I was on XFCE, but when the crashes started and I felt I had tried everything, I gave up and installed KDE Plasma from scratch instead, but the problem persists…

On KDE I followed (parts of) this guide: GitHub - ElizabethHarmon/ManjaroProAudio: A complete guide to setting up Manjaro for professional audio. - no pipewire and skipping steps 4, 7, 8 & 9.

Then I installed Qjackctl from pamac and Ardour 6.9 from ardour.org.

Since it still crashes on exit (window freezes and nothing is responding to mouse clicks or keyboard commands, but I can Alt-Tab to other programs) I uninstalled and got 6.9-5 through pamac.

I tried with a fresh user profile (deleting .config/ardour6 before starting) as well as a backup of my old profile. Now I’m stuck and reaching out for help.

What should be my next steps?

(Edited to clarify I’m not using pipewire, but jack / pulseaudio)

Start it from terminal and then close it. Post output. Edit: Does it dump core? coredumpctl -r

I installed it in VM just now, without doing anything from that guide and it opens and closes. But to be honest, I have no clue how to test it further.

I tried an export, then I had a different kind of crash (full stop and exit) and core was dumped:

Running from terminal, just opening a session and clicking ‘quit’ (the crash happens with any session I’ve tried so far):

Yeah that’s what I get.
Do you use pulseaudio or pipewire? Asking because the guide starts with installing pipewire, but later you said:

which is in step 10 and should be skipped.

Forgot to mention that I’m still going with jack and pulseaudio, so no pipewire (yet)

Was only going to suggest to switch if that makes any difference at all. Other than that, I honestly don’t have the slightest idea.
Try reporting issue upstream, if they have a bugtracker or whatever.
Or you can try to analyze that coredump if you can decipher anything from it.

Edit: fixed by downgrading glibc:
sudo DOWNGRADE_FROM_ALA=1 downgrade glibc
