Fail to build with stack + ghc-8.6.5 + windows

Hi, first of all congrats for your work with this library.
We are getting an error for the mentioned configuration (and only for that one, cabal builds it succesfully):

Ok, I get why this is manifesting. Uploaded ghc-lib-parser-8.10.1.20200523 to Hackage just now. I expect it to resolve this problem. Please let us know how that goes!

Oh and thanks for taking the time to report this!!

I've tested it locally and it works!
