First my error was regarding Wine not being installed. Then I got a startup error when I had Wine installed. I think I fixed the startup issue by changing my VM CPU to “host” instead of a virtual CPU in VM settings (Proxmox). Not sure if that was the same error you had, didn’t check my logs.

Hope it helps someone.

Found the issue i had to set the vm cpu to host in proxmox worked fine then
