Cant open Minecraft

I launch Minecraft on the launcher. It opens to the point where the mojang screen gets. Then gets closed and crash report. I know for a fact that full screen makes it crash. I tried to uninstall it a few times. Today It worked and opened but I tried to put it full screen then It crashed the whole game versions. I reinstalled, repaired, everything, but I cant fix it. Please help me asap. Thank you.
