You do not "run" the jar file. It is not an executable jar file. You use run.sh or run.bat depending on your operating system. See those files and user_jvm_args.txt for more information. If you can't get this to work, you need to speak with your hosting provider.

Your question is unanswerable in its current form. Don't paraphrase error messages. Show the real error/output and explain the steps you took to get that error. GUESSING: If you are clicking on the installer jar and it does not run, try this: https://johann.loefflmann.net/en/software/jarfix/index.html

optifine issue, make sure the version you have is compatible with the forge version you have.

Yes, and star worm equestrian doesn't have a 1.19.2 version so you must be trying to use the 1.16.5 version with minecraft 1.19.2 This won't work. https://www.curseforge.com/minecraft/mc-mods/swem/files

The name of the class in 1.19.2 is net.minecraft.world.entity.decoration.LeashFenceKnotEntity

Looks like you have a very old mod in your mod folder. LeashKnotEntity was the name of this class back in 1.16.5 The crash report alone does not identify the problem mod.

Yes, citadel now has error trying to modify the game code. But this could be a conflict with some other mod.

Something wants a different version of citadel to the one you have. You don't have the latest version of citadel. https://www.curseforge.com/minecraft/mc-mods/citadel/files If that doesn't fix it, it's likely you have some other mod that is out-of-date. You should contact the mod author to ask for help if you can't figure it out.

I assume you mean the damage that comes from the explosion? You will need to create your own projectile that creates an explosion that understands your logic. The other direct damage can be easily changed by overriding onHitEntity() Forge has an ExplosionEvent.Denotate that lets you decide which candidate blocks and entities are affected by an explosion. But if you look at LargeFireball.onHit() it just creates a generic explosion so you can't differentiate it from other explosions.

Forge's installer will work with java 8. But it won't work with an ancient version of java 8 that has expired trust certificates like the version of java being used here. The mojang (or curseforge, etc.) launcher will later download its own version of java that is valid for the game version.

Your question is unanswerable.

The error says your terminal is broken. Did you start the server from the command line then close the window?

Update your java or install a recent version https://adoptium.net/

Probably one of these? https://github.com/search?q=because+"p_130086_"+is+null&type=issues

Now you have a problem with simple planes. But given the error message it is probably caused by a different error not shown in the crash report.

Looks like an issue with krypton mod, check you have the latest version then contact the mod author.

Ask on their discord, I have no idea.

Looks like one of your mod files is corrupted/incomplete - it probably didn't download properly. The error doesn't say which mod file causes the problem.

It's not json. See BlockBehaviour.Properties.noOcclusion() or Blocks.GLASS

Can you access that url? Maybe you have some dodgy mojang addresses in your hosts file?

Or maybe it is because support has ended for 1.16.5 https://github.com/Jetug/PowerArmorMod/blob/a5b8089b7db5768af646f9776890aa1ce694b936/build.gradle#L37

mod ids need to be lowercase.
