CTRL being pressed constantly, can't type anything

Here's a weird one for you. I turned on my desktop this morning and found out that I couldn't type anything because it kept opening shortcuts that involve CTRL and when I tried to scroll in my browser, it would zoom in and out. So, I quickly found out CTRL was sticking so I thought it was the keyboard. I started searching around the internet (had to use my phone because remember, can't type anything), and all I found were "turn stick keys off." "It's your keyboard and I'll die on this hill". I used a keyboard tester website to see what was going on and CTRL was being pressed rapidly at random.. now here's the weird part.. Even when the keyboard was unplugged. It also did it with 2 other boards. I uninstalled drivers, updated drivers, ran commands in CMD, and rebooted a bunch. Nothing worked. It was only when I unplugged my SD card reader from the USB 3.1 port that the problem stopped. I plug it back in and the issue starts again... What even? I wanna go home, this universe is broken. What could have caused this? Anyone have any ideas? If we can pinpoint why this happened, is there anything I can do about it?

I unplugged the device the red arrow is pointing to and it stopped and allowed me to type. If I plug it back in (tested), the problem starts again. The problem now is why does this happen at all?

It sends the signals that the computer interprets as Ctrl on the keyboard. It's probably broken. Can you try it on a different system/device?

So I found out what the problem was. There was a broken USB driver because I ended up unplugging everything and the problem was still there, so I uninstalled them in hardware manager. I think the problem is solved. This would happen even if I unplugged every single device.
