Comment 8 for bug 2036362

But I don't know if this is related though, because the time of xdg-desktop-portal crash does not match the time of system crash. But I also have to mention, probably, that there was an older crash (maybe from 9th of September), but I deleted it, because thought it was not relevant. And the issue appeared a couple of days ago. I experienced it twice yesterday and I can't put my finger on it yet.

I've been reporting kind of similar bug (https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2000173) some time ago, but it got fixed with an update of the xorg package. I am not sure it is quite the same though, because as I remember, back then the audio was still playing and time updating, it was just that it would not react to any inputs ...
