After clicking play, the launcher proceeds to download the version as usual. However, once the game attempts to load, it'll show the crash message below. This has been happening since 18w19b and so on. I will attempt to uninstall and reinstall the launcher and such, and attempt to give feedback when I can. I'm also pretty sure that this happens to other computers that are weak like mine.

The crash report you attached looks outdated (it's from 1.12.2). Please attach the launcher log (.minecraft/launcher_log.txt) here instead.

The launcher_log doesn't say anything. Please scroll up in the game output window at the beginning of the repeating stack trace and attach it here.

I'm assuming this is MC-129374.
The obfuscated symbols are different, but similar.

I went ahead and added -Xss1M, as the post you linked me to said to do so.
I am finally able to launch MC, and I thank you for helping me.
