It works for me again on windows 7

The potential workaround doesn't work for me

I'm on Windows 7 and it looks like the TLS connection fails every time. Maybe the game is trying to use TLS 1.3 and it doesn't work.
(Stupid) workaround - Download java 17, copy the launcher from another computer, copy the version folder from `.minecraft\versions\<version>`  from another computer that has it, add the version in the launcher and configure it to use a custom java installation (it needs <java>/bin/javaw.exe). You may also need `.minecraft\assets\indexes\1.19.json`. And make a backup of it because the launcher tries to re-download and deletes it
