Did you do a command line update? If you did, did you run it using the same (operating system) user as the one that is running (web) php on your system?

I would make sure the permissions for your moodledata directory - and all its contents - are correct.

"cloud" => irritating, meaningless marketing term. At best, a catchall for computing power that's not yours. Says nothing useful about the functionality.
 
I'm so old that I learned programming in BASIC via a TTY33 and some time-sharing service. Surely, time-sharing was "the cloud" too?

Firstly, when did this start? Has the site always done this or is it a new thing? If the latter - what changed? Something did, even if you don't think it's related it.

When you say the site "hangs" is it just for the person doing the enrolment or is the site truly dead for *everyone*? While you are stuck are other people able to access the site normally.

I would try to see what the database is doing while it's stuck. Can you do a 'show processlist' during the "hang" to see what is happening?

Sorry - I misread that completely.

However, 4.1.9 was released on 12th February 2024 and (as you say) doesn't include any of those schema changes. They would have been in the update for either 4.3 or 4.5

At a glance, it creates new tables "scorm_attempt", "scorm_element" and "scorm_scoes_value". Are you saying that these are not there?
