Bug description

Installed 3.13.0 on Windows 11 and after starting to sync the client now freezes and when it does it causes Explorer to freeze as well.

When it does, Task Manager reports that the client is still utilizing about 10% of CPU resources.

The only way to get Explorer to respond is to End Task the Nextcloud desktop client.

Steps to reproduce

1. Install 3.13.0
2. Begin syncing
3. Both Explorer and the client will eventually hang

Expected behavior

I would expect that neither Explorer or the desktop client to hang.

Which files are affected by this bug

It's actually impossible to tell because I can't open up either the client or Explorer when it happens.

Operating system

Windows

Which version of the operating system you are running.

23H2 / 22635.3575

Package

Are you using the Nextcloud Server Encryption module?

Encryption is Enabled

Nextcloud Server logs

I don't have access to the server logs as I'm using Hetzner Storage Share.

Additional info

I can't even get to the "Create Debug Archive" because the application is frozen and unresponsive.

W10 22H2 / NC-client 3.13.0 / NC-server 29.0.0 / no encryption
NC-client crashes (no message, just stops) when trying to sync folder.
already have tried that:

docker exec -it --user www-data nextcloud php occ files:scan --all
docker exec -it --user www-data nextcloud php occ files:cleanup
docker exec -it --user www-data nextcloud php occ maintenance:mode --on
docker exec -it --user root nextcloud-mariadb mysql -u root -p'<DatabaseRootPassword>' -D nextcloud -e 'delete from oc_file_locks where 1'
docker exec -it --user www-data nextcloud php occ maintenance:mode --off

only fix is downgrade client to 3.12.3, then everything is fine !

I also synchronize the same folders on the same computer under Linux, no pb with up-to-date client...

I have the same error. 3.13.0 is not working on W11 (23H2). I also downgraded to 3.12.3 and everything is working fine again.

Same problem here. Client just crashes after sync started:

3.12.3 works like a charm

Same problem here. Client not responding even after killing and restarting the process. Also tried to kill explorer.exe to see if it was some kind on incompatibility but nothing... The linux client on my home pc works like a charm.
I'm now trying downgrading:
-3.12.5 does indeed not crash but also it doesn't sync
-3.12.4 crashes really badly

If this helps my server is self hosted on a raspberry pi with dietPi.

As 3.12.3 seems to be the last stable version, related to #6721 ?

As 3.12.3 seems to be the last stable version, related to #6721 ?

Interesting. It definitely appears to be related to VFS. If I disable VFS I can sync now.

Vfs = virtual files?

I do not use the virtual file system. So its not only related to VFS.

I had a similar problem with client 3.13 on linux (mint 21.3). I've upgraded my server to 28, it was the same: when starting nextcloud client, it will scan for files, then after it started to sync, it got stuck at 0% or 3%, then the UI was not responding. The CPU is at 100% and will eventually lead to the whole desktop being unresponsive (I had to reboot).

I've tried both the client from the distribution, and the 3.13 appimage, it was the same. I've also tried to disable bandwidth limit with no better behavior.

It started to act normally again when I've been back to the older 3.9.0 appimage.
