I run Debian 12 and ran into similar issues trying to mount NFS, even down to having to use an alternative console to log in and undo f stab edits

My solution was simple and so hopefully it helps you as well. In fstab, the backslashes don’t cancel out spaces. Since my directory path had a space in it, that would break fstab:

Path/to/your/Video\ Files breaks fstab

Path/to/your/VideoFiles good
