I had the same exit code by pressing Alt+F4, after trying to join singleplayer worlds or servers without success. The game was fully frozen in the "Loading terrain..." screen.
In addition I had the exit code "65540 invalid time inf" in the output log of the launcher. After some trying around and googling, I realized that my max. fps in the options.txt file was set to 0, so Minecraft's rendering engine has not had any chance to render the game. I had not modified the options.txt at all, so I have no clue how this could happen. The issue occured in 1.17.1, 1.18, 1.18.1. In 1.8.9 and 1.19 or newer it did not occur.
