00:00:06.597620 Guest OS type: 'WindowsNT_64'

Windows NT is not Windows 2019. There's a reason we have templates!

00:00:06.977308 VRamSize <integer> = 0x0000000001200000 (18 874 368, 18 MB)

18MB graphics RAM isn't much for a modern desktop OS. Increase to 128MB.

I see your virtual hdd is only 20GB. That doesn't seem like enough to do anything useful with a 2019 64bit OS.

The crash happens shortly after the virtual CD is accessed, so I also suggest a checksum check to test for a corrupted ISO / bad download.

Hyper-V is on.

Your log contains these lines:

{timestamp} HM: HMR3Init: Attempting fall back to NEM: VT-x is not available
{timestamp} NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

You might notice in the guest window's Status Bar the green turtle: The choice of animal is appropriate: Your guest is running, just really slow. Or it might guru-meditate. This is because a service that uses Microsoft Hyper-V is running on your host PC. Normally Hyper-V blocks Virtualbox. But your PC is of the type and OS where Virtualbox can attempt to run the guest using the Hyper-V engine. This arrangement is still being developed and isn't 100% yet.

If VirtualBox is running without Hyper-V enabled, and nothing else is interfering with hardware virtualization (VT-x / AMD-V), then the usual virtualization icon () will be seen in the Status Bar.

To turn Hyper-V off completely, do this:

1. Shut down all programs. You will have to reboot your host.

2. Look into I have a 64bit host, but can't install 64bit guests, 2nd post, points 2 & 3 and ensure that none of these things are running.

3. Find the Command Prompt icon, right click it and choose Run As Administrator.

4. Enter this command:

bcdedit /set hypervisorlaunchtype off

5. Enter this command:

shutdown -s -t 2

6. When the computer turns off, unplug it for 20 seconds. Then plug it in again and boot up Windows 10.

Your Virtualbox should be running now. If the green turtle still appears and the tell-tale lines are in the log, try all the steps again. If you don't get the standard virtualization icon, post back exactly what you did and we'll try to help some more.

And if Mpack's suggested hash check of the ISO works, it would be interesting if you can try the existing ISO after Hyper-V is off.
