Minecraft crashes on Mojang loading screen, what can I do about it?

Ca

Reinstall the launcher

ly

I already did but still not go

could that be due to optifine that I had but then deleted because minecraft crashed every 5 min ingame?

Da

Reinstall Java. This has nothing to do with the launcher itself.
