Dreaded "Guru Meditation" Error

[BrianVboxNoob]

Hi,

I'm using: VirtualBox VM 6.0.12 r133076 linux.amd64 (Sep 3 2019 13:34:02) on Centos

Recently, it started giving me this fatal error:

Guru Meditation

And inside the log I see:

I've done some googling, and reading here in the forum, and I'm guessing the problem was self-inflicted. A few days ago I was adding a second VM to my virtualbox UI and it was showing an error in the existing one saying I wasn't allocating enough virtual ram to the display if I recall correctly, so I upped it to the minimum it suggested. Now it's giving me this error. I'm not actually sure how to reverse it to be honest, or even if that is for sure the cuplrit. Would love some advice. thanks!
