The biggest problem: Hyper-V is enabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active)

Then, the wrong VM template is being used:
00:00:04.880774 Guest OS type: 'WindowsNT_64'


Delete this VM and make a new one. There is a 2019 template, but it may have a bug. Server 2019 will run in the 2016 template. Also check that the VM's System settings, Acceleration, Paravirtualization Interface says 'Hyper-V'. This is a comm channel provided by modern virtualization-aware OS's to talk to the hypervisor they're running on and is not the Hyper-V that blocks Virtualbox.

Also,
00:00:05.146072 NumCPUs <integer> = 0x0000000000000001 (1)

Server 2910 runs a lot better with 2 processors, and you have 4 hyperthreaded cores available.

RAM is tight on this host PC:
00:00:04.671107 Host RAM: 8101MB (7.9GB) total, 3604MB (3.5GB) available
00:00:05.146075 RamSize <integer> = 0x0000000040000000 (1 073 741 824, 1 024 MB)
00:00:05.146328 VRamSize <integer> = 0x0000000001000000 (16 777 216, 16 MB)

The VM's regular RAM setting may be too conservative. Set to 2GB. If video continues to not use 3D acceleration (on a server it shouldn't) then the 16MBvideo RAM should still be OK.
