My issue is almost the exact same as what everyone else's was... But I didn't even notice I could not crouch. All I saw was I could not draw my weapons. But all I have installed are weapon mods and they seemed to have broken the game for me. I have removed said mods but still the problem of not being able to draw my weapon persists. Each time I validate the files through Steam it says there is one file not validating and says it will fetch it but it doesn't seem to as I have to keep downloading more files over and over again. I will attempt the enableplayercontrols option but if that doesn't work, I am not sure what there is to fix this since the file continues to fail to validate. I have used the enableplayercontrols option and it allows me to crouch, draw my guns and fire them, but I am about to test if it works while I have the mods installed. It does work with the mods I have installed, but I had an instance of having to use the command twice as I flipped through my pipboy.
