VDP Management service start failed and can't get into VDP panel

Hi everyone

Now my VDP 5.5 can not start management service. I try starting many time and also try rolling back but it's still not come back to running stage.

Screenshot below show me everytime I try to start. When I press yes, management service be restored and then failed at last.

Do you have any idea ? This problem cause me to fail to open VDP on Vsphere web client. I have more than 40 VMs backup stuck on the VDP.

Help me please

Thanks in advance
