So when clicking the install button it should install the mods, but nothing happens when I click it. It does not say installing or anything. Literally, nothing happens.

Possible Solution

I've already tried to run twitch as the Administrator but it did not work. I thought the Java may be the problem but that's also not it.

This is a problem on the curseforge/twitch end. Been happening a lot lately.

Twitch App/CurseForge issue.
