Citrix VDA Session / Server disconnected after vMotion process with Nvidia A16 vGpu 16q profile

Hello everyone i have a big problem that the VM’s Server OS Win2019 with 128 GB RAM and nvidia_a16-16q and Citrix VDA 2311 on ESX8.0.2 after a vMotion Process, the users fly out of their sessions and can no longer reconnect.the Vm’s can also no longer be connected via RDP. The only remedy is to power off the affected VMs.
If vMotion is switched off, this problem does not occur.
The current Nvidia driver NVIDIA-GRID-vSphere-8.0-550.54.16-550.54.15-551.78 is currently being used.
