Nextcloud version (eg, 20.0.5): 22.2.2.0
Operating system and version (eg, Ubuntu 20.04): NextCloudPi version v1.50.0, NextCloudPi image NextCloudPi_docker_09-20-21, OS Debian GNU/Linux 10. 5.10.11-v8+ (aarch64)
The issue you are facing:
Today I noticed that my nextcloud clients did not want to login anymore. I tried the webinterface then and got the message that there were too many failed login attempts from my network. Digging a bit into my nextcloud instance showed, that all user accounts seem to be gone. Also, oc_users database table contains only ncp admin-user from nextcloudpi. ncp is the only user I can log in with anymore. The data of all the users seems to be still there in the data folder.
I have no idea how this might have happened. Can anyone advise me how I can recover from this state? I have a file base backup of my nextcloudpi docker volume.
Is this the first time you’ve seen this error? (Y/N): Yes
Steps to replicate it:
I have no idea.

the docker image isn’t updated yet on docker hub so we shouldn’t update the container yet, most likely an automatic update caused this for you, best to turn these off when using the docker image. You can read more info in these topics and on the test workflow I did in a GitHub issue, linked within the topics
