Why doesn't touchscreen work properly on Photoshop?

When I try to use the touchscreen on my computer to scroll or zoom in, Photoshop will act like my finger is my stylus and draw where I touch. It used to be that Photoshop would treat my finger as being separate from my stylus, allowing me to move my canvas with my fingers and draw on it with my stylus. For some reason, Photoshop has abruptly started treating my finger as a stylus. This started today. Why is this happening? How can I fix it? I am on Windows 11 Education.
