Desktop app causing Windows Explorer to crash

I am having the same issue, please hotfix asap.
Why is this still being rolled out by the autoupdater and why is it not fixed yet? it renders explorer unusable

It seems that the fix they proposed is working for everybody. This fix is part of the next NC 3.12.3 release that was released (on the github repository) yesterday:
Release Release 3.12.3 ยท nextcloud/desktop ยท GitHub and for myself it is already available on nextcloud.com and is distributed via update servers (for me).

Thanks everybody for helping to get this fixed.

I still hsve the problem. nextcloud.exe blocks windows file explorer. When I close nextcloud in task manager, as I cannot do it using nextcloud Icon, all the explorer windows open again.

Even after reinstalling latest nextcloud version problem persists.
