[Updated] Minecraft: Java Edition crashing or throwing 'Exit code -1' when using or opening Forge, but there's a potential fix
Here’s the crux of the article in video form:
New updates are being added at the bottom of this story…….
Original story (published on March 30, 2022) follows:
Minecraft is a popular open-world sandbox game where you have to explore, survive and build.
The Minecraft building system is full of possibilities, being one of the key aspects of the success of the game. The Internet is full of massive building projects of all kinds, from buildings to entire worlds.
On PC, Minecraft is available in two versions: standard (or ‘Bedrock’) and Java Edition. Minecraft Java Edition is available on Windows, Mac, and Linux.
You can expand the possibilities of Minecraft: Java Edition through Forge, which is a server that improves the compatibility of the game with mods.
Minecraft: Java Edition crashing or throwing ‘Exit code -1’ on Forge mods
According to multiple reports, the use of Forge mods is causing a crashing issue, an ‘Exit code -1’ message or a ‘Java Runtime Configuration may be invalid’ error message for many Minecraft: Java Edition players.
Hello, I am trying to play 1.18.2 modded but when I try and launch the game with any mods aside from those that are installed and launched with forge it will crash with an exit code 1 and says the Java Runtime Configuration may be invalid. I have re-installed Minecraft, Java and even downgraded the forge version but nothing works.
Some face the issue without Forge mods too
In some cases, the same ‘Exit code -1’ or ‘Java Runtime Configuration may be invalid’ message may appear to players who don’t have any Forge mod installed on Minecraft: Java Edition (1, 2, 3, 4, 5, 6, 7, 8).
Exit code: 1
Every time I try to launch Minecraft I get a screen that says Invalid java runtime configuration” “exit code 1” I don’t have mods or forge downloaded it’s just straight vanilla. I did download Minecraft before i downloaded java if that matters at all. I also get a screen that says “java exception occurred” any help would be appreciated
Also, some players suggest that all versions of the game (from 1.7.10 to 1.18.2) could be affected.
A potential explanation and fix
The issue could be related to the version for which the mod you install was developed. To avoid problems, you should install mods only on the version of the game for which they were developed.
General info: Always prepare for errors when your mods aren’t for THE EXACT version you play. For example, 1.18.1 mods might not work for 1.18.2 and vice versa.
The Java version on your PC could also cause issues. It seems that you should only install the latest versions of Java for Minecraft versions higher than 1.16. For Minecraft versions before v1.16, you will need to use Java 8.
This might be the cause:
Latest Java = 17 -> for MC 1.16+
For older MC versions use Java 8
There is no official acknowledgment of the issue from the developers yet. We will update this story if there is any change in the situation in the future.

Update 9 (June 22, 2022)
05:29 pm (IST): In case you’re facing the ‘Exit code -1’ issue with Minecraft while using OptiFine, then this might be the reason why:
Did you actually extract OptiFine instead of just copying it somewhere? Because the file name would suggest you didn’t. So… start the installer using Java and instead of installing it you’d extract it. Then copy the mod to the right location. (Source)
A user responded with this information to another individual’s complaint about getting the error code. Following the suggestion, the user did confirm that it indeed was the problem and the issue was resolved.
Thank you, that was the problem. (Source)

You mentioned you have magnesium which is just a fork of sodium. Magnesium references sodium’s code in its fork which is why it mentions sodium in the crash report. Disable that and try again. (Source)
