Can't press any button

So it all started after i make a settings like mouse sensivity slider and mouse invert checkbox. But when i started the game to test my settings, I can’t press any buttons or move the mouse sensivity slider. Why is this happening? I can press a button or move a slider before, but after some time the buttons and sliders don’t work. I’ve tried remaking it from scratch and the buttons or sliders work. but after some time the buttons and sliders don’t work anymore. Is this a bug or am i making some kind of a mistake? Help pls :<

Maybe it has to do with your anchor points of the button(s) and canvas/panel in general. Most likely you are test playing it in different resolutions of your play session window and the anchor points move or offset based on their alignment with the screen resolution.
Check your settings of the anchor points of parent object like the panel and the alignment of the UI elements and tweak it until it plays correctly in any resolution. Hope this helps.

but i can press the “back to main menu” button so… uh yeah :<
