You are assigning memory to your guest, that you do not have available. Either close some applications on the host, buy more RAM for the host, or reduce the amount of RAM assigned to the guest. Which you can't really...
00:00:02.257696 NumCPUs <integer> = 0x0000000000000002 (2)
00:00:03.095393 CPUM: Physical host cores: 2
You have assigned all your CPUs to the VM. The host is going to run low on resources, since VirtualBox cares about
physical processors (cores),
not logical ones (threads).
00:00:03.095304 CPUM: WARNING! Can't turn on NX/XD when the host doesn't support it!
You need to have the Execute Bit for anything greater than Win10. If you want to turn it on, look at your BIOS for the "Execute Bit" option.

Do you know how old your computer is? Well,
I do, because I have the same one!
That's an old system with not that many capabilities for the requirements that you're looking for. I wouldn't dare to run Win2019 on bare metal on it (let alone in a VM), it wouldn't take it...
