[Bug]: Nextcloud not responding which also causes File Explorer/ALL file access on Windows to freeze

[munrobasher]

This was what happened when I killed nextcloud.exe, removed (or rather renamed) the [accounts] section in config, re-launched Nextcloud and logged on again, using same folder:

The interesting bit here is about getting cleared. All this synchronisation is happening in a folder that is read-only for the users. They shouldn't be able to even add files to that folder. I'm going to do some further tests on read-only group folders as I my gut instinct is that's where the issue is stemming from.

I'm trying to repeat this in the lab on my own Nextcloud installation. I've managed to crash Nextclient client. All I was doing was using robocopy to copy a large folder (containing software) into a group folder.

There was a notification about not being able to sync a file which wasn't unexpected as robocopy was probably still copying it. But now I've got a red X on Nextcloud and I can't interact with the client. The Nextcloud process is using 0% CPU:

I stopped the crashed Nextcloud instance and restarted it - at which point it's started uploading the new copies files:

Here are the logs after restarting Nextcloud. NOTE: this on different platform and not exactly the same situation as the subject line but it's associated with trying to repeat it.

More logs from another user with same problem: Nextcloud client not responding and File Explorer won't open. My fix at the moment is to kill the process, manually delete some recently deleted folders in the read-only library, rename [accounts] as [accounts.bak] in config, restart Nextcloud.

Two sets of logs. Firstly the logs as I found them on the problematic computer. Second set after I enabled logDebug=true.

This is happening to me with fedroa 39, three different clients 3.12 .1 version, unofficial flatpak, official AppImage and distribution package, is not a package problem but upstream. It freezes after reaching certain file(s) that are not logged and cannot spot which those are. Errors are not logged.
