Best advice for a cracked screen and no insurance

My iPhone 12 Pro Max screen is cracked and won’t allow me to touch the keys 1/Q and - on keyboard unless I rotate it horizontally. It also won’t allow me to click the (<) button in random apps and/or different sections in apps. Is there any way to fix this problem without paying $100+ phone repair shop?
