Public bug reported:
The issue is happening 9 out of 10 times.
It is hard to get a crash dump in /var/crash during this error though, but I
found one from few days ago. Looks like should be relevant.
I've reported it, see OOPS ID: b68253a2-ea4c-11ed-af33-fa163e55efd0

It was difficult to figure how to send the report in Ubuntu 23.04, previously
it was just working... but with Ubuntu 23.04 there was this error:

Fixed by changing "Send error reports to Canonical" (in gnome control panel ->
"Privacy" -> "Diagnostics") from "Automatic" to "Never" and re-running the
`ubuntu-bug` command again.
