You cannot access this variable directly since it's private.
However, you cant write
$cm->uservisible
since this will invoke the __get() function that will return the private value.

It is slighly tricker than that, and the behaviour changed with PHP 7.4, it seems.

In some code, if someting tries to access $cm->uservisible, then that will indeed call __get.

However, for the cm_info class, __get does a bunch of complicated stuff, if any of the code called directly or indirectly by __get ends up making another attempt to access $cm->uservisible, then that will lead to the error reported here.

If you turn on developer debugging, then you can work out if that is what is happening from the stack trace of the error.

This is error shown in the moodle UI, any idea what might be causing this issue? This is blocker for us to move ahead.

Hi,

Is it happening in a single course or all courses? If in only one course, have you got a different course template??? If you turn on debugging, you could possibly find out what is causing the issue - something has to have changed - what has changed - the answer may be there.
