Accessing folder with dolphin crashes davfs2 since last update

I’ve been running davfs2 to have convenient access to a webdav folder. For the last year or so this worked without a problem. But unfortunately a few weeks ago there was an update and now it keeps segfaulting on me. The folder mounts just fine and I can browse it via the console. When I open the folder with dolphin it loads the content but davfs crashes in the process. console now shows “transport endpoint not connected” and dmesg reports

I can unmount and remount the folder just fine, but the problem occurs over and over again.

Has anybody experienced the same problem? And is there an easy way to downgrade davfs2 back to the version that was working?

Usually after a big update, AUR packages might need to be rebuild in order to function properly. Have you done that?

Thank you, I checked the post - and run the suggested commands. It seems there are no packages that are reliant on python3.9. However my davfs2 package was last build on Nov 5th, so this should have been after the last big update.
I did some more tests and an alternative file manager like “Files” can access the mount without crashing it. So the blame could also lay with dolphin (at least partly).
