Read the FAQ (orange banner at top of page) and post full logs as described there to an external site, and provide the link here.

These are the forge forums, you would need to ask wherever neoforged support is given.

Please read the FAQ (orange banner at top of page) and post logs as described there using an external site such as https://mclo.gs and post the link here.

Please read the FAQ (orange banner at top of page), and post full logs as described there using an external site such as https://mclo.gs It is very possible there is information in the log that could point to the problem, that is why posting the entire log and not 1 line is most useful.

Remove entity_model_features_1.20.1-forge-3.0.1.jar from your mods folder. If there are other mods that depend on that mod, you may have to remove them also.

Cracked launchers are not supported.

That failure is common in both logs you posted, if you remove the entity_model_features does that change things?

Just browsing through I see this Does it work if you remove that mod and try?

Always post new logs (as directed by the FAQ, do not post logs directly into your message as they become long and difficult to read) when you remove a mod or try something different. Chances are you probably have other client-side mods there, try searching the log for "Failure message", and trying what it suggests.

The error log suggests removing player animations, did you try that? Usually client side mods like that cannot run on a dedicated server. Also, please read the FAQ (banner at top of page) with regards ro sharing logs.

Cracked launchers are not supported, you must buy the game.

There are a few people that frequent the forums, but I would say most stuff probably happens in discord

Search your log for DEDICATED_SERVER and remove all mods mentioned in those errors.

Just to make sure, when you updated your drivers, did you get them directly from AMD? Don't use windows update to update them.

Please read the FAQ (orange banner link at top of page) and post logs as described there to an external site (such as https://mclo.gs) and post the link here.

In that case, I would open a bug report issue with the mod author, explaining the issue you are having, and explaining that removing that mod fixes the issue.

There is no jar file for that version, you just run the .bat file What is the exact problem you are having? What are you expecting to happen when you dbl click on the .bat file? *also, please read the FAQ, and post relevant logs to an external site. Also make sure you are using the correct version of Java for 1.20.1

That server is running Fabric, and these forums are for Forge support. You would be best served looking for help wherever Fabric support is given.

That doesn't mean you can get Fabric support here lol. I mean, you might get lucky and someone that knows will answer, but your best bet is wherever Fabric support is given, probably a discord server.

Always post new logs after trying something and it doesn't work Should help narrow it down.

Looks like it's the obscureapi mod Someone also commented on their curseforge page that the same issue randomly crashes their server.

When someone asks "Does it work without <mod name>?", that usually means "Remove <mod name> and give it a try, it may be that mod (or version of that mod) causing it". If it still breaks, post new logs

These 2 mods are the same, remove one of them.

What launcher are you using? That's the weirdest log I have ever seen. Does it work if you use the official Minecraft launcher? Also, seeing this error: Caused by: joptsimple.ValueConversionException: Directory [<APPDIR>\Instances\Robot Rockin O] does not exist Which I would take as indicating the game directory doesn't exist.

I have split your reply into a separate topic, you should not just reply to someone elses problem with a "me too", especially without posting any logs or anything. You may or may not have the same issues they do, especially if you tried the posted solution in their topic, and it did not solve your problem. Please read the FAQ (orange banner at top of page) and post logs as described there to an external site such as https://mclo.gs and post a link back to it here.
