I want to remove some independent mods and I get an error

[shrewd ibex]

Helloo. I want to remove some mods like the aether with the add-ons, the blue skies, and others I don't remember their names, and it gives me an error. I don't know why, if they are independent. So I'm asking for your help if someone can give it to me. Thank you

From what modpack?

[shrewd ibex]

Sorry, from better Minecraft 1.20.1

[elder venture]

I’m not sure that those would be good to remove from the pack.

[shrewd ibex]

Ok..

Have you idea what mods can I remove?

[elder venture]

Have you tried the modpacks without modifying them first?

[shrewd ibex]

Yes, and that's why I want to remove some mods that aren't interesting for me, like the already mentioned

For example, I replaced the backpacked for the sophisticated backpacks, and it works. But when I remove other, Minecraft gives an error

you can just ignore the ones you're not gonna be fussed with really, there's a lot of mods that are crucial to the core of the packs so taking them out can cause loads of problems especially for recipes, quests, etc

[shrewd ibex]

I also want to remove the one from the quests.
That is, I want to remove them so I have to load fewer mods and free up my PC resources a little.

it's pretty well optimized as is, are you having issues or just don't have a lot of space on your computer in general?

[shrewd ibex]

yes, some problems in world rendering and fps
