Whenever I attempt to change the game's video settings, it results to:

The game crashed whilst mouseclicked event handler
Error: java.lang.ExceptionInInitializerError
Exit Code: -1

I have been dealing with this ever since I first started using the mod.

In the future, please use the templates they exist for a reason. For example, I’m fortunate that I know that crash occurs when you try to use Sodium on 1.16.2. If not, you and I would have wasted a lot of time trying to investigate this.

You’re attempting to use Sodium on 1.16.2, which it doesn’t support. Currently Sodium only supports 1.16.1. This is a known issue and will be fixed when it’s updated.

It was 1.16.1 for both...

Please provide the full crash log. You can find it in the .minecraft/crash-reports folder. The latest one should be the one with your issue.

If you do not see or cannot find it, please provide the full latest.log file from .minecraft/logs

[note from person reporting the crash on github: yeah, ik my specs are kind of slow. but it usually gets past this without the use of sodium]

Duplicate of #211 and #219. Something is wrong with Sodium’s config file. If you’ve edited it manually, you’ll need to fix it to make the file valid JSON. If you’re using other mods that are breaking this file, report it to those authors.

Your config file is corrupted. Delete the sodium-options.json file from your game's config folder.

In the next release, Sodium will reset the config file to default rather than crash if it is invalid.
