I bought a realm 8/1/22. Prior to buying realm, I logged into my minecraft account just fine. However, after I purchased the realm and logged back in to finish registration of the realm, my whole computer crashed after just barely launching. When investigating further, I found that when minecraft started launching, my CPU peaked really fast and reached 100% almost immediately during launch, therefore crashing the computer.

I have tried pretty much everything to fix this. I have completely uninstalled and reinstalled minecraft. I have tried to change the allocated RAM. I even tried to overclock my computer, which worked until the main screen until crashing. I have tried absolutely everything I can find on Redditt and online, and it still keeps crashing.

It only crashes when I am playing version 1.9 and 1.9.1. This happens on both Java AND Bedrock edition. It also crashes on the snapshot. Which, since I just bought a realm, is very frustrating.
