Assumnig the above didn't work, then another option is to check that you are running the latest verison of Minecraft Forge. Minecraft Forge works for the Java Edition of the game, so if this is the version you use, this could well resolve your problem.

You can to the official website to check for any updates, and install them if you aren't already on the latest version.

As above, if there is a compatibility issue between the mods you ahve installed, and the version of Forge you are running, this could explain the issue you are experiencing.

Deactivate All Your Mods

Last, but by no means least, is the option to switch off all your mods. While this may be an option you wish to avoid, it may be the case that one specific mod is at fault. And you're going to have to do some detective work to figure out which one it is.

So start by deactivating all your mods. Then, reactivate them one-by-one, checking the game each time. If it works normally, then you can leave that mod alone. But if it throws up the error, then you will need to leave that mod inactive, or uninstall it, if you want to play the game.

If you have got this far, and you;re still experiencing issues, then we'd suggest reaching out to Mojang Customer Support. You can report a bug, and they may be able to suggest some alternative fixes for you to try.
