Minecraft won't start, why? - 1

From time to time I play minceraft for a week or something like that, now I hadn't played it for about a month and thought to myself I feel like doing some round bed wars again.

I started the launcher and the latest update (1.16.4) was downloaded automatically.

When I start the game I get this red Mojang loading screen and the loading bar stops at about 80%.

I have already deleted and reinstalled the Game + Launcher, downloaded new graphics drivers and started an older version of the game. Every time I come to this loading screen and get an error message (see appendix).

I hope someone can help me.

I would try to reinstall Java (Java 8 presumably because it doesn't work with newer versions, at least for me).

That is also a strange story. That happened to me on Windows too. Actually (and I know that because I'm a programmer) the JVM is backwards compatible. Actually, that shouldn't happen. And now under Linux, with the OpenJDK, that doesn't happen either.

I can't really explain myself either.

For me this also happens under Linux (Xubuntu) with the OpenJDK (version 11). I can't explain it to myself either.

Interesting. Because I'm using OpenJDK version 14.0.2 under Arch Linux. And I have no problems. Well, that's the way it is with Java: You never really understand what exactly happens.
