Fatal Error after update to 2.3.0

I just updated a WordPress 6.1.1 installation to Redis Object Cache version 2.3.0 and got the following error after flushing Redis cache:

PHP Fatal error:  Uncaught RedisException: socket error on read socket in /usr/www/users/wp/wp-content/object-cache.php:561
Stack trace:

#7 /usr/www/users/wp/index.php(17): require('/usr/www/users/...')
#8 {main}
  thrown in /usr/www/users/wp/wp-content/object-cache.php on line 561

Only a rollback to 2.2.4 fixed it.

Is this a known issue? Can I change some settings to prevent this or hs this something to do with the new Predis version?

Thanks for your help!
