Using Fedora 42 Workstation and mounted a Windows 11 shared drive. The first time I tried to use a file it generated a long sequence of errors concluding with:
[FAILED] Failed unmounting run-user-1000-dc.mount - /run/user/1000/doc.
[FAILED] Failed unmounting run-user-1000-gvfs.mount - /run/user/1000/gvfs.

It then locked up tight forcing a hard power off.
After a reboot it seems to be working (so far!)
