Desktop client downloads files it shouldn't

I recently installed the Nextcloud desktop client on my new notebook and now have the following problem. For some reason, the client downloads random files that were not requested. Sometimes I clicked on “Free up storage space” several times. Nevertheless, it keeps starting to download files that I’m not currently using at all. And I only have the problem on this one specific computer

OS: Win11 23H2
Nextclod Client: 3.12.3
