Bug: Process "gjs" uses a lot of CPU - no desktop icons - computer freezes quickly

[kojid]

Since today, my computer doesn't show desktop icons and the fan gets very loud. I found out that the process gjs uses a lot of CPU. When I open programs, the whole computer gets very slow and eventually freezes completely. After reboot (remove battery), zorin boots normally but gjs still takes a lot of CPU and the problems start again.
Anyone facing this problem as well? What can I do to solve it?
Quitting the process doesn't help.
Also, sudo apt reinstall gnome-shell-extension-zorin-desktop-icons doesn't help either.
My Zorin 16.2 Pro is up-to-date

Can you post your computer specs or a screenshot of screenfetch or neofetch?

I see them usually to 0, virtual memory and memory instead is other stuff .

One manages Gnome shell notifications while the other manages Zorin Desktop icons.

Thanks for your quick reply.
I found the source of the problem. Files names containing German Umlauts (ä,ö,ü) were automatically renamed quite some time ago. For example,
12ü3.pdf
was renamed to
12�3.pdf (ungültige Kodierung)
Ungültige Kodierung means invalid encoding.

I don't know when the renaming happened, it was quite some months or even years ago. Today I copied such a file to the desktop which made all desktop icons disappear, gjs using lots of CPU and freezing the computer.
Changing the file name in nautilus fixed the issue.
