Failed to create a snapshot of the virtual machine: Win Server 2019 guest

[Charlweed]

I cannot snapshot any Win Server 2019 guest.

I can snapshot a guest before the OS is installed, but after, it refuses to snapshot or export. Guests are stopped when I attempt. I have created multiple guests to attempt snapshoting, all fail. Dispite the error message, the NVRAM file is copieed to the destination directory, but vbox fails anyway. I have checked permissions and selinux. I have tried temporarily changing the value for the "Guest OS" selector, and the "Graphics Controller"

Version VirtualBox 6.1.10 Host CentOS linux kernel 3.10.0-1127.13.1.el7.x86_64

Guest info file.

Log, but its probably not relevant, because the guest is stopped when the error occurs.

Correction, I can export Win Server 2019 guests, but I cannot make snapshots.
