Strange behavior under Volumes with external SSD

[RRZEurope]

I have a Mac mini M1 and an external 2TB SSD where I have my user accounts stored, since the internal is a bit limited space-wise...
after upgrading to OS 12.5 I ran into the problem that the login never worked (spinning wheel forever)

After some hours I found the reason - the Admin account worked (on the internal SSD) and Terminal showed
drwxrwxr-x@ 13 myname staff 416 17 Jun 17:05 Macintosh SSD 1
drwxr-xr-x 20 root wheel 640 14 Jul 10:48 ..
d--x--x--x 3 root wheel 96 29 Jul 15:09 Macintosh SSD

so the external SSD is now mounted with the name + " 1". at the end

When I rebooted, pulled the SSD and logged in with the Admin account the "Macintosh SSD" was still there and I removed it by
sudo rm -rf "Macintosh SSD"
and it was gone .. until I rebooted and the same occurred again the "Macintosh SSD" and (the actual physical ssd) "Macintosh SSD 1"

Anyone an Idea what I can do ? At the moment I changed the external accounts to the path (/Volumes/Macintosh SSD 1/user/..) and it works - at times (sometimes I have to login with the admin account before the login with another user is possible - no idea why)

Not a solution to the particular problem: why not leave the users on the internal and then symlink the individual subfolders e.g. /Users/whoever/Library, /Users/whoever/Documents etc. as well as /Applications to the external SSD?

I did that before, but since you could change the real path in the extended options, I choose that over symlinks - some apps did not really work well when installing stuff in the library via symlink (cubase)

SOLVED:

It now works, but I don't really know what caused it...

SOLUTION: I changed the port on which the SSD is connected and retried the "sudo rm -rf /Volumes/Disk" when the disk was disconnected - after the next reboot, I now have just one single Mountpoint
