Zenworks Agent 24.2 from May not work with Android devices in managed device mode

Since last week we have problems registering Android devices in Full Managed Device Mode (afw#zenworks). The Zenworks Agent is downloaded, but stops immediately after starting before the login window with login and the ZCM server entry appears. So it can't have anything to do with the ZCM server. The same hardware was successfully enrolled in April of this year. These are devices with Android 8 + 10.
As far as I can see, the current app (24.2.0) in the Playstore is from May of this year.

Does anyone have similar problems and maybe a solution? I guess, it is not possible to go back to the agent version from April 2024.

Thank you very much.
