1.21.80.26
I've got the same problem.
Minecraft crashed when entering a world (singleplayer or multiplayer). The console didn't show up any information about the crash. After updating the driver for the nVidia graphic card the window was still open. There was about 20 seconds where the game reacts. Then the screen holds and the game crashed. There was still no information about a crash. Also no crash reports where generated at the standard location. The only information the log shows is that minecraft can't keep up the system. It's running over 4000ms behind and skipping about 80 ticks.
Even more RAM for Java didn't worked as expected. The options where activated through the launcher.
It is reproducible within the same environment. After a fresh install the problem still exists.
