Two days later, no user owned a database record. The activity would day no records and offer to enter one. All the records are there in the database but owned by the teacher!

The CSV I uploaded looks like this:

Email address,shelluser,shellpassword,Approved
user000@example.com,user000,9ecbacd1,0

I don't know whether e-mail alone is not sufficient. But just after I uploaded the records were nicely owned by the corresponding users.

Somehow the logic is not intuitive to me. Not trying anymore, since the need was solved by other means (not Moodle-based).

Are you sure that you problem is identical to that of the OP https://moodle.org/mod/forum/discuss.php?d=449111#p1804900? Is your teacher also using SEB?

If not, mixing you problem with somebody else's "similar sounding symptoms" muddy both discussions. In geek talk, "thread hijacking".

Marching a Moodle site and what platform(s) to use are two different things:

- March route: Where you want to go? Get it from https://moodledev.io/general/releases. The the planer is here http://www.syndrega.ch/blog/#php-and-dbms-compatibility-of-major-moodle-releases.

Pay attention to the maximum(!) versions of the compatible system software.

- Platform: Yes, people take what they are familiar with. I have a full series of (some historical) Debian Linux VMs to march Moodle. If you know XAMPP well, then take XAMPP.

Not counted are the additional plug-ins. After such a long time the probability is high that some of the plug-ins have been abandoned.

"deathly afraid" Take all kind of backups, Site_backup, Course_backup, Question_bank backups, ... And don't burn your bridges. ;)

I remember a single case where the Moodle sessions were on a network mounted drive which was unstable and confused the session handling, users were logged out as well as mixed up! The base technology, PHP and sessions are otherwise in use world-wide in gazillion of sites. Ask for the LAMP stack.
