This apparently started to happen somewhat recently, as I've been able to run GHC 8.2.1 on Windows before. (Perhaps it was a recent update that changed things?) In any case, any attempt to run GHC or GHCi 8.2.1 immediately results in an access violation, and always at the same memory location:

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 8.2.1

$ ghc
Access violation in generated code when reading 000000001170399e

$ ghci
WARNING: GHCi invoked via 'ghci.exe' in MinTTY consoles (e.g., Cygwin or MSYS)
         doesn't handle Ctrl-C well; use the 'ghcii.sh' shell wrapper instead
GHCi, version 8.2.1: http://www.haskell.org/ghc/  :? for help
Access violation in generated code when reading 000000001170399e

Strangely enough, GHC 8.0.2 and older do not suffer from this issue, just 8.2.1.

In case it's useful, here's the strace output:

$ strace ghc
Access violation in generated code when reading 000000001170399e
