Hello!
I have a different behavior of this issue: after hanging for about 30 minutes, Windows Server 2019 boots like nothing happened. During those spinning dots, I can ping the vm but I can't do anything else. I tried to look in Group Policy and nothing seems off. The VM is part of a group policy in an organization. It is annoying that every time we have an issue that requires reboot we need to wait 30+ minutes before doing anything else. I should mentions this VM has more that 180 virtual disks attached to it - could this have an impact?
Thank you!
