My game crashes when starting up. It opens to the Mojang screen and stays there for a minute or two and then crashes. I could get the game to load yesterday but not today. This may be unrelated but I have been getting lag in my main world over the past couple days. The game has also had issues loading when going through a nether portal during that same time, some times it would just take a very long time and other times it would crash. I have tried resetting in the windows settings and uninstalling/reinstalling and it still wont open.

Nevermind turns out I needed to update and restart my computer. I should have done that first. I would delete this but I don't know how.
