Joomla told me "installation succesfull" but then "Class "Joomla\Plugin\Behaviour\Compat\Extension\Compat" not found" appeared. No chance to log in.

Welcome to the Joomla forum!
The missing class is declared in the file plugins/behaviour/compat/src/Extension/Compat.php. Does that file exist?
Locate the file administrator/cache/autoload_psr4.php and delete it. Access Joomla 4 again and the file will get recreated automatically. This file is a map to all PHP classes Joomla uses and it is created and maintained automatically.

Do you have a backup to restore that is recent? This may be an easier more crude way to solve it...then look into why it maybe happening.
