Failed to start vm

Description

After going through the update of TrueNAS Core 12 to 13u1, there were problems booting the virtual machines that had already been created, fortunately it was a test environment, wait for a next update, 13u2 and a next 13u3 and so on until 13u6 and I continue with the same failure to start the vm.
I emphasize that of the 8 vm that you have, only 2 turn on correctly.
marked error:
OSError
[Errno 22] Invalid argument
remove_circle_outline
