What is the configuration of the system you're running Workstation on?

You need to be a bit more specific on what happened. "the machine never boots" or "it never came up" are very vague descriptions.  

Does the boot hang? Does it drop into a PXE boot prompt?

Does the virtual machine configuration meet Windows 11 minimum configurations: TPM, UEFI Securie Boot, 2 CPU, 4GB memory, 64GB virtual hard drive?

Did you verify the checksum of the download ISO file?
