I've been trying to log on all week, and I can open the launcher just fine. I'll select which version I want to play, 1.16 or 1.15.2, and when I hit play it continues like normal. Then, the moment the minecraft screen opens, the window freezes on the white screen that appears before the Mojang logo appears. I've let it sit for hours at a time, it won't load. I've uninstalled both Java and the launcher, and re-installed them, and the problem persists.
