Is this the first time you’ve seen this error?: yes

Can you reliably replicate it? (If so, please outline steps):
just open NextCloud

The issue you are facing:
Administrator->logging full of enties:
PHP Startup: Unable to load dynamic library '/usr/lib/php7/modules/memcached.so' - Error loading shared library /usr/lib/php7/modules/memcached.so: No such file or directory at Unknown#0

memcache.distributed is not enabled in config.php so why it looks for it ? There was no such errors in 11.0.2.

The output of your Nextcloud log in Admin > Logging:
PHP Startup: Unable to load dynamic library '/usr/lib/php7/modules/memcached.so' - Error loading shared library /usr/lib/php7/modules/memcached.so: No such file or directory at Unknown#0

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

If still relevant
This path won’t exsist it must be /usr/lib/php/7.x/modules/memcached.so
x = your version. Example if you use php 7.2 you must write /usr/lib/php/7.2/modules/memcached.so
