It appears that the days of simply being able to export a VM and import it into any Host you like are over. With Windows 11 requiring that the VM has TPM turned on in its Settings, and that if the Host that created it also has TPM turned on, then when such a VM is exported and imported to another Host the imported VM fails to run with the error: "the key protector could not be unwrapped"
At first I thought this meant the VM was a Shielded VM but I'm increasingly comming to the conclusion that it may just be down to the need for the VM to have its own TPM if it is to run W11. More on this, first posted over on Ten Forums as my first Windows 11 VM that could not be exported and imported successfully was created on a Windows 10 Pro Host machine.

fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October.
