[02-Sep-2023 21:02:13 Europe/London] PHP Fatal error:  Out of memory (allocated 23068672) (tried to allocate 270336 bytes) in F:\moodledev\moodle41\theme\snap\classes\local.php on line 37

Therefore the code does not properly check to see if the plugins are there, it only (I think) relies on the setting being set (the default).
