After deleting ALL Java installations (included the MC Launcher.) and ONLY installed Java 8 ("sudo apt install openjdk-8-jre"), it worked! Thanks for the help!

Ok, I will try to find a way to delete it.

openjdk version "14-ea" 2020-03-17 OpenJDK Runtime Environment (build 14-ea+18-Ubuntu-1) OpenJDK 64-Bit Server VM (build 14-ea+18-Ubuntu-1, mixed mode, sharing)

Yes, I used "sudo apt purge openjdk-14-jre" and "sudo apt purge openjdk-14-jdk" and still, it crashes. One thing to note: Minecraft gets to the FML Early Loading thing, but it crashes right after that.

I looked at my log and it was still using Java 14. I used "sudo apt purge openjdk-14-jre" and I still got: I uninstalled Java 14 but still got this.

I recently got Minecraft: Java Edition on my laptop. If I play Minecraft 1.15.2 Vanilla then I can play normally without any crashes, but when I play Minecraft with Forge and 0 mods then it crashes. 1.12.2 Minecraft with Forge crashes but gives no output. 1.15.2 with Forge gave this error: The game crashed whilst initializing game Error: java.lang.ExceptionInInitializerError: null LOG 1.15.2: LOG 1.12.2 I have no idea as to what is causing these errors, I have OpenJDK-8-jre, OpenJDK-11-jre, OpenJDK-14-jre, and OpenJDK-8-jdk. I mostly want to play Minecraft 1.12.2 and Forge but if I can't get that working the 1.15.2 with Forge will work too. Thank you in advance.
