my VM Centos 8 starting kicking me out

[Saca]

This morning I had a pop up to reboot my Window server for updates.

Before I rebooted Windows, I went over to my Linux CentOS 8 VM and gracefully shut it down.

After it was completely down, I rebooted Windows.

After windows came backup, I started my Centos 8 VM, it took a very long time to start, but eventually my sing on GUI was up, I was able to login and open a terminal and ran a few commands, suddenly it closed my terminal and went back to the sing on GUI.

I went to Oracle VM VirtualBox Manager, clicked on File, then clicked on Check for updates, I received "You are already running the most recent version...". Since the version number did not show, I looked at Help - About VirtualBox - I was running 6.1.8.

I starting googling and found that the latest version is 6.1.12, so I downloaded and installed it. I also install the latest extpack and the latest guest additions.

After the CentOS 8 reboot, I was able to login and work for about 15 minutes before it kicked me out again, back to the sign on GUI.

This is screen that It opens, after it closes my session and in few minutes it is back to the sign on GUI

SO just to be clear. it is ont the Virtualbox VM that is failing on you, but once you are logged in CentOS8 after some period of time X session kicks you out and you land back on the CentOS8 login screen?
