No shell can be opened: Error: Could not fork child process: There arre no available terminals

[Stefan Berger]

Hello!

  It looks like a recent update of cygwin is now not letting me open any shell anymore. I get the following error with the Window frame showing 'nologin' in upper left corner:

Error: Could not fork child process: There are no available terminals (-1).

I have tried to apply security exceptions for nologin and mintty via Windows settings.

The Windows settings I have used can be found under 'Privacy & security' -> 'Windows Security' -> 'App & browser control' -> 'Exploit protection settings' -> 'Program Settings'. I added 'C:\cygwin64\sbin\nologin.exec' with its full path and added 6 overrides so that everything is now 'off'. I did the same for bash and mintty  but it does not resolve the problem. Any help would be greatly appreciated.

Thanks,
   Stefan
