Updated to 5.2.8 and got a black screen with underscore after GRUB

[YoungSith]

Hi, I just updated VB from 5.2.6 to 5.2.8 and both of my VM's worked perfectly (Ubuntu Desktop and Ubuntu Server) and now when I press enter to boot Ubuntu in the GRUB it goes black screen with the tilting underscore... I really need to access the information on my Ubuntu Server VM so I really need help and I'd appreciate any of it! I'll attach the logs for you. Thank you!
