Game crashes on 1.12.2 with exit code 6

[Lordpun]

I've been trying to use Forge for a 1.12.2 mod using the Prism Launcher and I've been getting crashes with exit code 6.

The console log is this.

I've tried running Optifine as a test mod and I have tried running with no mods, but both gave the same result.

Same issue with another Launcher like MultiMC or AT Launcher?

[Lordpun]

I haven't tried any other launchers, but I was getting the same results when I tried using forge with the vanilla launcher.

Maybe it refers to an issue with the system - check for CPU/GPU driver updates

[Lordpun]

I checked for any driver updates, but no new updates were found

Keep on using the original Launcher

Run Vanilla 1.12.2 once and close the game

Download Optifine and run optifine as installer (click on the optifine jar)

Start the launcher and make sure the Optifine profile is selected - then test it again

I tried both Vanilla and Optfine like you said, and both gave the same result. So I believe the issue is most likely with Minecraft in general and not Forge

Does it work with newer versions?

For 1.16.5 also make a test with Embeddium + Oculus as Optifine replacement

Of the newer versions I have tested, 1.21.5 does work perfectly fine, but the only others I have tried, being 1.12.2 and now 1.16.5 with the mods you suggested showing the same results of crashing with exit code 6.

Maybe it refers to an issue with Java 8

 

Install this version:

https://www.azul.com/downloads/?version=java-8-lts&os=windows&architecture=x86-64-bit&package=jre#zulu

In your Launcher, change the Java Executable o the new java 8 installation at

C:\Program Files\Zulu\zulu-8-jre\bin\javaw.exe
