Logging into servers and opening single player worlds crash my game.
I've tried logging out of my account and logging back in, turning launcher visibility on, adding both Minecraft and Java 8 to whitelists/exclusions to anti-virus programs. I have Avast, Malwarebytes, and CCleaner. Windows firewall isn't a problem. Restarted computer multiple times. Both the servers and my game are on 1.12.2, no mods. Been searching EVERYWHERE, all I've seen is "it's a common problem", but none of the fixes I've found have helped.

Curse PremiumUpdate your drivers.
Intel E7400 Bearlake drivers
and your GPU too.
YouTube? www.youtube.com/clockpie5436
^^ plase sub as it does help alot!
Need help with anything? Message me!
I can halp you with most MC related problems.
Figured it would be something with those. My computer's too old for a lot of things, and my family is short on money to get a new one or even fix up our current one (GPU's are fairly expensive). Well saves me the time of searching for an answer. Thanks a bunch! Hopefully I can get this fixed, at least now I know the problem.
