[Bug]: Always getting "Encryption App is enabled, but your keys are not initialized. Please log-out and log-in again."

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

Server side encryption doesn't work anymore since NC31, which is released a few days ago.

The key initialization message always showing up. Login... logout... login... logout... The keys don't be initialized and encryption cannot be set. Tried it on a fresh new installation as well as an upgrade from previous NC (which broke my installation). Tried it multiple times with a fresh new installation, disabled master key before enabling the module in the admin settings.

Steps to reproduce

Setup a fresh new NC31 (Nextcloud Hub 10) installation.
Enable encryption module app and in the admin management settings.
Login as user, logout as user, login again... repeat...

Expected behavior

Key initializing after re-login and encryption can be enabled and working as expected an written in the documentation.
