Shift, Command and Option don't work in Photoshop! Please help!

So I recently got a new Wacom Intuos Art Medium tablet and whenever I try to use the eyedropper tool in Photoshop (option key) it shows the eyedropper icon, but when I go to move the cursor with my pen it goes back to the tool I had selected before pressing the Option key.. I also tried using the command key to move something but it changed back to the tool I had selected before. The thing is I can use the keys fine when using my trackpad, but when I try to use the wacom tablet, that happens.

Here is a video i recorded showing the problem: PLEASE HELP!!! - YouTube

This also happened to me on Animate CC.

I've tried so many things but they don't seem to work (downloading a plugin, reinstalling the driver, resetting tools, quitting programs etc.) It's really frustrating! Please help!!
