Bug description

We have a Nextcloud 23.0.3 server for a customer which uses Nextcloud 3.4.4 Desktop Clients to sync the files to their PCs with Windows 10. The folder size of the log folder (C:\Users[username]\AppData\Roaming\Nextcloud\logs) is getting very large in a short amount of time. Our customer regularly deletes all files out of this folder, when it gets as big as 100-200 GB. After just a night almost 10 GB appeared again. The folder permissions are set to full-access for the user, Nextcloud is also run as the user.

When the folder is getting very big, a lot of 1-2 GB as well as 400 MB log files can be found. This state in the screenshot is only after one night, so its not as big.

We did setup the folder synchronisation from scratch to see if something would change. Now also updated on the latest version of the client, the problem still persists.

Steps to reproduce

1. Set up folder synchronisation with Nextcloud client.
2. Wait a time.
3. Check C:\Users[username]\AppData\Roaming\Nextcloud\logs for big log data.

We couldn't reproduce the error though, so it doesn't seem to affect all PCs.

Expected behavior

Log files should be deleted after a short time or maybe get file size capped to not generate log folders as big as 100-200 GB.
