Using this mod, Optifine for Minecraft 1.21.1 is having issues loading, and cannot be loaded. What I have done is downloaded the proper jar file necessary from Optifine's website for Java 1.21.1, and inserted it directly into my mods file. I have evaluated all of my mods to only include the ones that are compatible with Optifabric and Optifine. I have also downloaded Optifabric for the appropriate version and installed it as well. The game launches, but immediately displays an error that shows that it has failed to load Optifine and recommends me to report the issue. Due to a lack of versions of Optifabric for Java 1.21.1, I will also list the link to the website that I used in case it is illegitimate.

Hope that the issue can be resolved, thanks in advance for help given.

If this solves your issue please close this ticket.

Ok then

There is currently no Optifabric version for 1.21+. Until such time you will just have to wait for the release or find an alternative to use. If this solves your issue please close this ticket.

Hmm. Then how did I get that? Anyway, thanks for the info, when will the 1.21+ version be released?

You will have to wait for Chocohead or someone else to make/port optifabric to 1.21+, but until then there is no other option to use Optifine until a viable Optifabric versions is created. If this solves your issue please close this ticket.
