I don’t know if this will help you but here goes anyway:
On an android box, after kodi and then the wookie are installed, if you turn the box off from the turn off button, you will get some or all of the problems that you are getting.
The only way to avoid it is to pull the cord off the android box after install otherwise the installation will not take properly.
So what I am saying is after you install the wookie, you need pull the cord off the box, but how do you do that on a computer without risking other damage.
Control alt delete is the only way but in your case it would seem that is not enough.
So just for once after you install the wookie shut it down somehow with a shock like pulling the mains lead off.
This is probably what it needs, same as we do on an android box.
But I’m not taking any responsibility if anything goes wrong, do it at your own risk
