Bug description

Newest update to the Windows client for Nextcloud has introduced a new issue where Explorer will constantly crash and restart.
Event viewer in Windows says that ntdll.dll has something to do with it, but the only solution I have found to fix the issue is uninstalling the program, and rebooting.

Reinstalling does not fix the issue.

Steps to reproduce

1. Install latest version of Nextcloud Windows client
2. Perform any task in File Explorer
3. After a few crashes of Explorer, it becomes more and more unstable.

Expected behavior

Being able to freely use File Explorer.
