Solaris 11.4 in the same computer: "vga_arbiter" error

hi,
I put a VM with Solaris 11.4 back into an Intel 2019 MacBook, but now Solaris doesn't start and after the two boot lines it gives this message
root pool not found pci0...
vga_arbiter attach_node_hierarchy failed
Than Parallels show a message "The virtual machine processor has been reset by the operating system"

That VM was already in the same computer, but maybe the setting are now different. I don't understand why...

Please, any help?

Salvo

 

here the first errors

 

any help, please?
I think the problem is something into Parallels 17.1...

 

Is there any update for this issue?
I'd love to get Solaris back on both macOS Intel and ARM.

Thank you
