@danyg #13 no, no other patches applied. I tried it once, it failed and I reverted to default module file.
Told the content guy to use intelli-sense on the name, which helps a little. Looking forward to the update.
We're still on php 7.4.33. Don't know if that has anything to do with it.
I tried the patch in #6 and got this error:
ParseError: syntax error, unexpected 'if' (T_IF) in _registry_check_code() (line 155 of [website]/sites/all/modules/entityreference/plugins/selection/EntityReference_SelectionHandler_Views.class.php).
