If I want to add a new entity reference field to webform entity on a paragraph type I get a WSOD.
Error: Call to a member function getPluginDefinition() on null in tagify_options_list_alter() (line 60 of modules/contrib/tagify/tagify.module).

I think the assertions in hook_options_list_alter are not enough to make it fail proof during runtime.
By documentation it should be only a debugging/testing feature.
https://www.php.net/manual/en/function.assert.php
I opened a merge request with early return's.
Thanks @sunlix to report and fix the issue.
Moving to RTBC and Fix, it will be part of the next release 1.2.24
