### Additional info

As mentioned in https://github.com/nextcloud/desktop/issues/6349, changing the bandwidth limit to 512 KB/s didn't solve the issue, and as mentioned in https://github.com/nextcloud/desktop/issues/5779 I can't tell if some of my local files have this issue, but the sync succeeded last week ¿¿??, and experiencing the same reported here https://github.com/nextcloud/desktop/issues/6791.

The only major change I've made is migrated my server hardware to a new box, but as I use docker for my NC setup, I think everything may be the same.,

Just to mention that I've uninstalled clean all my NC client packages, also deleted the NC client folders in my home directory and also went to every folder formerly synced and deleted all sync dot files and such, then reinstalled NC client with apt from scratch.

Start by reviewing debug_archive.zip and reproducing the hang with the large-folder sync configuration described in the issue on Linux Mint. Trace where the desktop client becomes unresponsive during synchronization and compare its behavior with the server PROPFIND log entries; done means the large-folder sync completes without leaving the client unresponsive.
