Mouse click 1 bug

I was tweaking my config.ini file, I set my A button to attack click and my mouse 3 to attack click, I haven't changed it in a few days, today out of nowhere without tweaking it, my mouse1 now does not work, mouse3 works as mouse1 and I replaced my old config.ini with my new one and changed everything back to it should be, restored defaults to keys in game, that didn't work, I researched it, it told me to delete the config folder entirely, open the game, it re-sets its default config, still did not work, I uninstalled the game, deleted game folders then completely reinstalled, still did not work, tried manually changing the config.ini to button 1, still does not work, I think this is a bug and i've seen a few posts and a few youtube videos about it all unanswered and none were solved, does anyone have any fixes?
