Whenever I try to launch a Minecraft version under 1.13 (1.12.2 and under) then it crashes before I can even see the Mojang logo. The launcher_log is attached. Also, I had to put 1.15.2 as the affected version because it wouldn't let me put "1.12.2 and under" as the affected versions.

I'd suggest you to go to the Minecraft Launcher bugs section that is right here https://bugs.mojang.com/projects/MCL/summary
This is for java in game issues
Have a nice day though
