Hello,
Below might indeed be the case.
To verify try running Remove All widgets Node after Input change. You could also try Set Focus to Game Viewport. There is also a node Has Mouse Capture that returns boolean. You could do a dirty check by running Get All Widgets of Class and see if you indeed have one eating the input.
Edit: try running Get All Widget of Class → User Widget. Should return an array, check it’s length. That’s how many widgets you have.
Maybe this will help you narrow down the issue.
