My trackpad has suddenly stopped clicking. Even when I connect a usb mouse the cursor will move but clicking the mouse doesn’t do anything. How do I fix this?

It could be a swollen battery pushing up on the bottom of the trackpad, making it act is if it is being continuously pressed. This would make it ignore clicking from the USB mouse.
