Please read the FAQ (https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/) and post logs to an external site, and link to them here as directed. This will provide information that will hopefully provide a solution to your problem.

This is an ancient thread, you should read the FAQ, and make a new post, posting logs as described to an external site, and linking to it in your post.

These are the Minecraft Forge forums, you should probably ask for Fabric support wherever they give Fabric support for best results. (https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/ very first item listed there)

Post a new log after removing that mod, may point to the true culprit, or be a completely different error entirely.

GitHubException in thread "main" java.lang.RuntimeException: ja...Context Unable to enter the game Crash Report https://mclo.gs/k5areKjFound this doing a google search for "ClassNotFoundException: com.simibubi.create.foundation.utility.Lang", it was the first result.

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.
