After upgrading to PHP 8.2, dropping an element into the form just says "Please wait..." forever, and the item does not get added.
The javascript console says "500 error"
The drupal log says:
TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in element_children()
Any fix for this, for those of us being forced to upgrade to PHP 8.2?

After upgrading to PHP 8.2 version. Then most facing issues in the code like
"TypeError: count(): Argument #1 ($value) must be of type Countable|array"
Solution :- check that variable is array or not. Or use is_countable function.
e.g. $a = is_countable($b) ? count($b) : 0;
Thank You
