Virtualbox is usually quite clear on the error message, though what it means can be hard to determine. You'll need to be more explicit with what Virtualbox says in the error message box.
Your guest "guru-meditated". The log says the guru meditated over a "Triple Fault", which means the guest tried something that Virtualbox really did not understand.
The guru meditated a few seconds after the guest starts the install ISO:

I'm not certain there is any Virtualbox setting to set the guest's page file to any value. Perhaps you mean the guest's virtual drive?
You're a bit ahead of the times, apparently, which is OK:

the log wrote:VirtualBox VM 6.1.12
But the guest wants too much memory:
00:00:03.136892 Host RAM: 7069MB (6.9GB) total, 3070MB (2.9GB) available
00:00:03.504840 RamSize (in the guest) = 0x0000000100000000 (4 294 967 296, 4 096 MB, 4.0 GB)
Shut down host programs, log off & on again, try to clear more host memory, or you'll have to reduce guest memory.
