Game won't even appear or generate a crash log. Every single version after 1.12.2 crashes as I click the play button, and every single version before 1.12.2 works 100% normally. Already tried changing profile's directory to force fresh files/folders.

Please do not mark unreleased versions as affected.
You don't have access to them yet.

Pleas attach the launcher log if you can't find a crash report in (minecraft/crash-reports/crash-<DATE>-client.txt)

Didn't actually know that feature existed. There's your log!
Wrong log.
Please attach the launcher log (.minecraft/launcher_log.txt) here.

Launcher log, attempt #2, here it goes.
