Client Version leads to Corrupt World

We are unable to play on the Server via Windows 10 and xBox, but under iOS it works fine.
When we walk a few steps (~2 chunks) or go through a nether portal, an error message comes up. The World is than corrupt. If we use the old Server-Version 1.17.0.03 again, it is all fine. But under 1.17.1 it fails.

Also the Version Number is somehow Different between the Windows-Install and the Number in the Welcome-Screen. Therefor I post the Build Version. Hope this helps more.

Client Error Message:

Disconnection due to world corruption
Attempt to reopen the world or restore it from an older backup.

(My game runs in German. Sorry.)
