Inventory and Character screens unusable as they just continously flash

When trying to use any keyboard functions outside of games (hitting Q to open inventory, C for character, etc) the screen opens briefly then continuously flashes and cannot be used. It’s as if the function is constantly opening and cleaning though she is not continuously mashing the buttons.

Steps to Reproduce

Don’t believe it can be as my wife has the issue and I am not having it.

What I expected to happen

Hold inventory button and inventory opens without issue. As well as other commands in the plaza and other places.

What happened

Has happened since she installed the game.

Notes / Media

I will attempt to record a video and update this post when I can get to her computer.
