[e-users] e-crash issue

Hello,

The flashing phenomenon occurred once, but I was unable to record it
due to a concurrent e-crash, and will do so at a later date .

Another problem now.

I often download web files using the browser Vivaldi, and occasionally
(but I feel it is more often than not) I get an e-crash.
Until now, I thought it was probably caused by Vivaldi, but....Today,
after updating pipewire and wireplumber.

   $ systemctl --user daemon-reload
   $ systemctl --user pipewire pipewire-pulse wireplumber

on the shelf, I couldn't see the Mixer icon on the shelf anymore, so I
clicked on that part and it caused e-crash, and I panicked and pressed
the F1 key.

This made me wonder if the e-crash could have been caused by something
else.
So, I uploaded the .e-crahdump.txt file.

I have put the file as e-crashdump.txt.gz at the following location.

Could you have look?

I would appreciate your advice.
