Bug description

Nextcloud Desk client stops syncing files after a while and goes haywire. E.g. server notifications are disabled but when the problem happens, the whole status window if full with repeated server notifications, e.g. " created 20m ago", " created 19m ago", " created 18m ago".

Steps to reproduce

Unclear. Let the client run for hours, I guess?

Expected behavior

The client should continue to sync properly and should not start going haywire.

Linux version : Ubuntu 22.04.2 LTS (Linux tnn-NK50S5-SZ 5.19.0-50-generic #50-Ubuntu)
Nextcloud Desktop version : nextcloud-desktop/jammy,now 3.9.1-20230725.181132.d02a998aa-1.0~jammy1

Have a similar problem here, the desktop client worked for a while, and then began to loose control : the fan become noisy, the CPU raised a lot, no right click actions work (no setting window, no nexcloud window), and of course the synchronisation doesn't work anymore.

i've tried snap version, reinstall the last version, install the ppa, tried wayland change proposal, nothing works.
if i try to launch nexcloud by cmd line, i have no warning or error messages.

weird problem !
