Hi Alessandro,
I still have no clue about what's going on.
I tried to clone the machine but the same error showed up again. I thus believe it is related to the VM itself.
According to what you say, I guess it cannot be related to the OS as my VM is running Windows Server 2019.
The only "solution" I can think of currently is to start over with a brand new VM.
I'm really interested if you find clues about this.
I contacted the VmWare assistance but I don't have an answer yet.
Good luck to you and regards,
Félix
