Not really sure what you can do if the --safeMode doesn't work, to be honest. Evidently just starting the server (I assume you ran it once you added forge/mods) was enough to embed those datapacks into your save. Hopefully there's something that can be done for you, and someone will chime in with a solution! Good luck!

The problem is the save is expecting the mods it was run with, probably due to there being items/blocks/etc in the world from those mods. Try adding --safeMode to your commandline that runs the server, and see if that works.

You can either fix your datapacks or reset to vanilla with --safeMode

Which would mean we should have a vanilla log, but that's a forge log you posted?

I think you forgot to post the link to the log. See the FAQ for more info on how to post logs properly (https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/)

What if you try with Java 17? Was just looking at https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/ where it lists Java versions for which version of forge. *edit: And you don't need the x86 packages, just the 64 bit ones

When you click the link and it takes you to the ad page, do you wait the 5 seconds, and click the red Skip button at the top right? Just did it for recommended 1.20 build and it worked fine for me using Firefox. If it still doesn't work, try clicking the +Show All Versions, point at the little (i) next to Installer for the version you want, and click the link for Direct Download.

More information is needed, there is nothing in your post to go on to help you. Do you have the source for this mod? Is it open source? Does it have configuration files? What are you trying to change?

Immersive Aircraft, Sophisticated Core, ModernFix, Tweaked (computercraft), Create Big Cannons, and Create are attempting to access the client classes, which do not exist on a server.

Unfortunately, just the error code makes it impossible to know what is wrong. Please post logs as described in the FAQ (https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/)

You could try posting a log (if there is no log at all, it may be the launcher you are using, the FAQ may have info on how to enable the log) as described in the FAQ, however this will probably need to be reported to/remedied by the mod author.

Post logs as described in the FAQ, there might be a clue in there what is going on.

The registered recipe name doesn't need to be the name of the item, so name one ruby_from_block and one ruby_from_nugs or something like that. Without seeing code/project files, that's the best guess I have.

I am unsure what you are trying to say after "When I launch the run.bat", is it failing to run and just immediately saying press any key to continue? Or is it because it is launching a vanilla server, not a forge server? Which is what will happen (if it is launching something), since you're specifying the vanilla jar file, and not the forge one. Please read the FAQ and post logs as described there, it helps to see what's going wrong.

Please read the FAQ on how to post logs. You have client mods trying to load on a server, which will not work. The one that stuck out was sodium client extras, there may be others, they would probably be easier to find in a log post the way the FAQ describes.

That looks like it!

The company that made the graphics device, as far as I can tell it appears to be using AMD Radeon graphics.

That log still says something is already bound to the port. If it's not showing anything running, perhaps there's a stale lock file or some other strange thing going on. If possible, perhaps a server reboot?

Can you post a new log? Just don't want the port in use error to be the cause of the server not starting:)

From the original log you posted: Check that another minecraft server isn't running on that machine using port 25565

I don't see a crash in that log, is it the complete log? If not, try reposting it

Please post logs as described in the faq, they contain more useful information.

Please post a log as described in the FAQ, it may have more information to help.

Have him update his video drivers, from the manufacturer website, not Microsoft update, and see if that helps.

See the FAQ, cracked launchers are not supported, buy the game.

Possibly, but to be honest I don't think I've ever seen a modpack that didn't have a ton of warnings and non-fatal errors, due to poor coding and incompatibilities between mods. So is it the server or client crashing?
