http error 500 in wp-admin after update to 3.2.20

Hi,

after updating to 3.2.20 I get an http error 500 in the WordPress Backend.
I restored a backup of the whole site and updated all neccessary plugins one after another. Again after update of “Theme and plugin translation for Polylang (TTfP)” I got error 500.
No big deal for me – honestly I don´t even remember why I once installed the plugin and everything seems to be translated well. But I thought you should know.

What can I tell you?
WordPress 6.1.1 – Theme ENFOLD, LiteSpeed webserver, PHP 8.0.26
