How run more than 1 CS:GO Instance

[ipio]

Hey,
I need to run as many CS instances as possible on my computer.
Sandboxie was fine at first, but now I get "VAC Error" all the time.
I see, it's very hard to fix it/impossible to fix it.
I also downloaded VMware workstation pro 17, unfortunately there is no gpu passtrough and cs just does not start.
I was thinking of some vertigo boost panel and just using it to run my CS instances, but couldn't find any that worked.
I need all these instances to boost the server's stats.
So the question for you is what are the working methods to run several instances of CS?
Actually, I'm thinking about installing proxmox VMs because they have gpu passtrough and test it there.

Think you can still use Avast Sandbox to do it.

Set steam to run as admin and set steam to run in Avast Sandbox.
