MinTTY Shortcut Nonfunctional, Unable to Launch Shell

[R0b0t1 <r030t1 at gmail dot com>]

Clicking the icon I created that launches mintty directly does not
work. Launching Cygwin.bat from C:\Cygwin64 gives me:

      1 [main] bash 9772 fork: child -1 - CreateProcessW failed for
'C:\Cygwin64\bin\bash.exe', errno 13
bash: fork: Permission denied
bash-4.4$ logout
      0 [main] bash 10684 fork: child -1 - CreateProcessW failed for
'C:\Cygwin64\bin\bash.exe', errno 13
bash: fork: Permission denied
bash-4.4$


If I then hit Ctrl+D to log out, that bash session is closed and I am
dropped into my shell with the proper prompt:

If I launch mintty from PowerShell, the window appears without
incident, however the PATH is not set properly.

I found this post
(https://groups.google.com/forum/#!topic/git-for-windows/AHeS_8PXz2w)
which mentions Cylance. How can I detect if Cylance is getting in the
way? How can I run mintty at all if that is the problem?

Thanks in advance,
     R0b0t1
