It's been a couple of days since you posted this, I hope you figured it out by now. But nobody replied so just to be sure:

It could be that you have two copies of two mods? Try disabling one version of each mod and try again. Or maybe one of your mods is outdated. If it's none of that, then you might have to tediously disable all your mods, then load one each time you load the game until you find the one causing the issue.

Typically for crashes on opening, the first thing to look at is if you have the latest version of the mods, and if the mod has been updated for 1.21. A lot of mods still haven't.

If I had to wager a guess I'd say that it's most likely "drtagx" causing the issues. I don't see any other mod that'd touch the moon except the shader.
