Critical Error when I try to open a VM in proxmox

[AdriAlvaro]

Hello! I'm trying proxmox for my first time and I created a MV on proxmox but when I try to open it I get a critical error in the node I installed the VM

My PC specs in case it could be useful:
32GB RAM
i7-9700K CPU 8 cores
I use to open 4 mvs at the same time (3 cluster proxmox and 1 more - using a total of 7 cores + 2Gb RAM each vm)
Here is the log file

Does anyone know why could it happen?

Thanks in advance,
Adri

I would like to attach Log again since I can't find this error in any forum's post:

00:06:16.969345 !! VCPU1: Guru Meditation -1149 (VERR_EM_INTERNAL_ERROR)
/
00:06:16.974548 emR3Debug: rc=VERR_EM_INTERNAL_ERROR

Any ideas?

Please try a newer VirtualBox version. This issue was probably fixed in VirtualBox 6.1.20 almost a year ago.
