Hi,
We may try to wait for some more time, maybe it hasn't finished installing the Hyper V role.
If the step is totally stuck, we may try to force a shutdown of the machine, then try to boot in the safe mode, check if it could work.
Below is an article about how to deal with stuck on "Getting windows ready don't turn off your computer", for your reference:

Besides, I'd like to check what is the edition of Windows 10, please check if the Windows 10 meet the requirements to install Hyper V role:

Thanks for your time!
Best Regards,
Anne
