Minecraft crashes when loading world while connected to Internet

When I attempt to load or create a world while connected to the Internet, Minecraft crashes. When I am not connected to the Internet, loading worlds works flawlessly. This only affects worlds, I can still join and play on servers. This bug is also very inconsistent. When a new update comes out, it stops. But after a day, it comes back. Please help, this bug has been affecting me for a couple of months. I thought the Village and Pillage update would fix it, but it hasn't apparently
