Zombies breaking and not moving is a known game bug in Unturned.
Happens worse on some maps, especially Polaris A6. Unfortunately, the only current fix is restarting the server. https://github.com/SmartlyDressedGames/Unturned-3.x-Community/issues/2884
The servers restart daily on non-peak off hours, wait until then and the zombie issue will be automatically fixed. In the future, we hope the game developer will release a patch to fix it.
Update Dec. 2023:
We have provided relevant server logs of the error & details to Nelson (game developer). Problem is with the pathfinding the game uses. He's tried two patches to resolve the issue already
