Does not activate the keys

[Henriko Magnifico]

The program itself is working without any errors, but it doesn't seem to actually activate any of the keys it gets as input. I've tried multiple programs (notepad, atom, WordPad, VirtualBoyAdvance-M etc.) but it doesn't do anything in any of them. I'm running Windows 10, Python 3.9 x64 and PyWin32 3.9 x64.

Any help would be much appreciated!
