PHP was throwing an error due to the fact that explode was being passed directly as a parameter of the array_pop function, which causes an error because the return value of explode must be set against a variable before being passed to a function. See this article for more information/an example of where this occurs.
To fix this is now being set against a variable before being passed to the following function.
Tested with PHP 7.3, WordPress 5.7.2 and MySQL 5.7
