I am adding a comment because I have the same issue on one of my test Win10 machines. I tried the solutions here and found elsewhere on the web, but nothing has helped so far.
I do have a Win10 machine that will run Sikuli - same Sikuli version. The difference is the Windows versions. The one that Sikuli does not run on has the Red Stone 5 (1809) update installed - the one that works has Red Stone 4 (1803) still.
I am thinking this may be the issue - as I have uninstalled various KB updates to see if one of them is causing the error. None of the uninstalled KBs helped.
