You have been subscribed to a public bug:
Sometimes randomly it seems the wifi gui just crashes. Sometimes in the
process of connecting/disconnecting. Even tho the laptop had only an
uptime of a few minutes. After the wifi gui freezes my complete bar on
the bottom freezes. Sometimes I get the report systemd crashed: wait or
kill process (i think). Then everything crashes.
After that I always press the power button for 11 seconds after which
the laptop starts again normally.
I checked with journalctl --since "2025-10-05 10:00" --until "2025-10-05 11:20".
And found this:
