watchdog BUG soft lockup - CPU#0 stuck: Could it Be Issues with Nested VM With Unraid + VirtualBox?

I have VirtualBox running Linuxmint in a Linuxmint VM Host inside Unraid. It was working well before, until recently, it failed to boot.

 

Error on screen is :

watchdog: BUG: soft lockup - CPU#0 stuck for 23

I tried the following when troubleshooting the issue:

1. Reverted VirtualBox back to previous version: Same Result

2. Switched to Legacy, then, KVM, then Default Virtualization in Virtualbox, also tried Legacy: Same Result

3. Booted the VirtualBox Host bare metal: No issues at all, so I suspect there might be issues with the nesting.

 

I don't remember doing any heavy reconfiguration in Unraid that might have caused the issue, just installed the most popular plugins like; CA, UAD, Fix Common Errors, others. 

 

Any ideas, how to troubleshoot and fix the issue?

Is it VirtualBox or Unraid Issue?
