Windows freezes after reattaching an FSLogix volume

Hello,

after we restarted one of our windows server maschines, where our FSLogix vhd containers are located, windows freezes after fslogix tries to reconnect to the container. Windows does not catch itself anymore and only a reboot helps.

Is this a familiar Bugg? Is there any solution?

FSLogix Version: 2.9.7838.44263
