Same issue here. The thing is that it just started happening one update.

started happening one update

If you could figure out which version caused this issue we will be able to fix this quite quickly.

It works with my xbox controller but not the keyboard controller.

That’s interesting

I think I have figured out the issue. The issue is that Ryujinx does not stop inputs when you open the keyboard, the inputs are still being pressed in the background. For some reason, the Stardew Valley Developers decided to check every frame whether or not you are pressing A on a textbox and pop up the keyboard. This makes sense because with an xbox controller, you are able to control the background while the keyboard is popped up. Another thing is, if you hold A while on the text box, the console spams, however if you let go, the console comes to a halt.
