Nextcloud-client: strange automatic behavior

I initially installed the nextcloud-client through the official Fedora repository on a freshly installed Fedora 39 XFCE spin. Unfortunately, I observe very strange behavior. Nextcloud-client automatically starts every time I commit to downloading a file in my browser, every time I save a LibreOffice document, or once I commit to converting a book in calibre. I thought that there was a problem with the repository’s version of nextcloud-client and decided to uninstall it in favor of installing the flatpak version. Sadly, the same behavior is observed with the flatpak version of Nextcloud. I would like to ask you, could you please suggest how to fix this annoying issue with nextcloud-client? Thank you very much in advance! Cheers!

Possibly report the issue to the Nextcloud client team (ie not Fedora), it sounds like an upstream issue.
