@dani3c, @masakmand @chouby
This trick worked for me:
In the Permalink-Settings /wp-admin/options-permalink.php i changed to the first option to call the page with id.
And than back to the option with url-alias.
Now they are working fine.
Hi @dani3c, did you get an error-Message in log?
It seems not to work. I had trubble yesterday and i get the message, that my version of polylang is not compatible with my version WP 6.4.1
Some ours later there was a update for the plugins and with the update images are shown. But all settings ar lost.
