This is the Forge forums, only Forge is supported here. Forge is still available for newer versions like 1.21.1 and 1.21.8, you can find downloads for these on the files link on at top of the website (or here). Despite having "Forge" in the name, NeoForge is a separate thing, leading some to call it "Neo". You can learn more about Neo's origins here.

Where are you applying the flags? What does "JAVA 17 compatibility mode" mean? Forge 47.4.8 has a minimum of Java 17 to match Minecraft 1.20.1, but also works on Java 21.

The second link you posted looks like a latest.log file. A crash report is formatted differently and does not have timestamps beside each line

The log appears to cut off without any errors. If you don't have a crash report (in the crash reports folder instead of the logs folder), then unfortunately all I can suggest is a binary search... Backup any world saves you care about first Set half the mods aside and run the game with the other half If it works, the problem is coming from the half you set aside. If it doesn't work, the problem is in the half you've kept. Keep splitting until you find the culprit(s) Remove the culprit(s) and add back in all the other mods Restore your world saves backup

Online forums in general seem to be declining in popularity imo. There’s still value here for certain types of content, such as written tutorials and blog posts which would otherwise get lost in the chat history fairly quickly on Discord. Also for those that prefer the forums format ofc. But for faster support related topics, I agree that the Discord is probably your best bet at the moment. The speed of responses is also down to the ratio of volunteers - the player support forum still seems pretty active, but the coding ones much less so. Once you’re feeling more confident in your modding skills, be the change you want to see

1) Update to the latest build of Forge for your MC version. The recommended build actually means minimum recommended. I can’t remember if it was backported to 1.20.1 or not, but we did clean up the early loading screen a bit in newer builds to look less cluttered. 2) Change the accessibility setting in game to black background. The early loading screen will then be black instead of red.

public ExampleMod(FMLJavaModLoadingContext context) { var modEventBus = context.getModEventBus(); } Refer to the javadocs and MDK for more pointers and examples.
