Try jarfix (provided you indeed have java installed)

You should post full logs as per the FAQ (https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/)

If you delete (make a backup just in case) the config file mentioned in the error, does it load?

Does it work if you use the regular Minecraft launcher? Also, please read the FAQ about how to post logs, pasting your log directly into your forums post makes it hard to read, and makes the post pages and pages long.

If you add 1 mod, does it crash? If you change which 1 mod you add, does it still crash? Which mods are you adding? What modpack are you starting from? A log from adding 1 mod and having it crash might possibly be helpful as well. It is entirely possible the mods you're adding are incompatible with other mods in the pack, or the way the pack is configured.

These forums are for Minecraft Forge, not Fabric. Your question would be better asked where Fabric support is given, likely their discord server.

Please read the FAQ about how to properly post your logs, it makes it easier for people to help you. Remove those extra mods, then add them back a couple at a time, testing in between. This will allow you to determine which mod you are adding that is broken/incompatible.

Please read the FAQ on how to post your logs; embedding them in your post like that makes them very hard to read, which may make it harder for people to help you. I'd be interested to know if you run into the same problem(s) if you create a fresh world, vs loading into the one you've been playing.

Please read the FAQ about how to post your logs. Posting them in a spoiler is much harder to read with the formatting/line wrapping, which in turn makes it harder for people to help you.

Search the log for the word FATAL, and sometimes (not always) it will tell you exactly what's wrong.

Please read the FAQ for information on how to properly post logs. When you just post them embedded in your message, they are harder to read, which makes it harder to help. I did notice this though, which means you are missing a mod required by a mod you have installed:

This question would probably best be asked wherever fabric support is given; these are the Minecraft Forge forums. They aren't the same thing

Just realized that Optifine is installed, if you remove that does it still break? Often times "performance enhancing" mods will break stuff, especially if there are more than one installed.

When you make a change, you should always post a new log if it is still broken

If you're using Ryzen onboard graphics, they are AMD graphics, so same thing will apply.

If you are using an AMD graphics card, update your drivers directly from their website, do not use windows update to update them.

Please post your logs as described in the FAQ. Directly posting them in your message formats them in such a way they are hard to read, and makes the page have a lot of scrolling to get to the bottom, which makes it harder to get help. As far as I can tell, it looks like oculus is trying to do a mixin with sodium, and it's not finding what it wants to change. If you remove one or both of these mods, does it launch? Having complete logs would likely show a bit more information, as per the FAQ.

Please read the FAQ (https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/) and post your logs in full as described. Partial logs such as you shared in your post do not contain enough information to troubleshoot.

Firstly, please read the FAQ about how to post logs, as just pasting a log into your msg makes it harder to read, and harder to navigate the thread to reply (and also get help!). I'm curious, does it still crash if you remove the modernfix mod?

Firstly, please read the FAQ about the suggest way of posting your logs, just pasting them into your forums post is much harder to read and navigate than having them on a paste site, with the link posted here. From the looks of it, if I had to guess, I'd say you world got corrupted somehow, did your server power off without properly shutting down the MC Server? If you have a backup of the world, I would try loading that backup from a separate save folder to see what happens.

Please share your gradle.properties file

More information is needed before anyone would be able to help. Please read the FAQ, and post your logs as described there, and hopefully that will have enough information to find a solution.
