PVZ GW2 bug stops all inputs for whole PC

Hi.

So I've been having this problem where, randomly, when playing GW2 on PC, all inputs stop working. Not only in the game, but like my mouse is not moving, microphone stops working, no keyboard key does anything. Alt+f4 does nothing, not the windows key, nothing. I even tried doing something on my drawing tablet, and even that didn't achieve anything. I've tried unplugging all the devices and everything when it happens but the only option is shutting off power from my PC and restarting it. I've tried editing the launch options with the -RenderDevice.IntelMinDriverVersion "000.1000" as well, but that didn't fix anything. I think I'm having a different problem from that anyways, since the game works and all my inputs work, sometimes for hours at a time but it just randomly cuts everything out.

And yes, this only happens on GW2, any other game I've played hasn't had this happen, ever. I do apologize for the lack of attachments, since my computer stops working every time this happens so it's not like I can take a screen recording of it. 

Does anyone have any ideas or ways to help? I've been having a good time playing recently, even in the midst of all the hackers and everything, I've been getting some good games in. This bug just understandably ruins the whole gaming experience, especially when it happens during an online game.
