VBR Proxmox VM-Backup not possible - Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)

Question

Hi all, my first entry here :-)I use the Community Edition of VBR for backing up two proxmox-vms. Installation was no problem and worker was configured. If I backup linux-vms there is no problem. But if I try to backup two windows server 2022 vms (image for hpe proliant server) i get the error: Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx). If i check the guid in windows with power shell the guid seems to be good. I tried serveral things but it is not possible to do a backup.Anybody a solution or the same problem? Daniel
