So instead of looking through Forge's events package you've written into your mod to sub to the base event and identify each one manually as it's fired?
I don't understand why this is such a prevalent issue, I can understand broken configs but every broken config that is reported has the same break.
Delete the config and have it regenrate.
CMD and Batch are the best ways by far,
however if you NEED to be able to double click on jar files to run them make sure you have Java installed in the first place and try this: https://johann.loefflmann.net/en/software/jarfix/index.html
Pixelmon are not properly indicating in their mod that it requires a certain (or subsequent) version of Forge.
This version is identified on their website but not in the mod itself please bug them about it: https://pixelmonmod.com/discord
Please don't make posts like this, especially less than an hour after your original post.
It looks like you didn't follow the installation instructions of one of your mods, you appear to be missing a dependency.
