Installed resource pack not appearing in resource pack menu

Last night when playing 1.17 for the first time I realized that I would need to delete the Vanilla Tweaks resource packs I have installed and install their 1.17 compatible counterparts. Today I tried installing the resource packs back into my game, following the instructions on Vanilla Tweaks website. After placing them into my resource packs folder I came out of the resource packs folder in my game menu and went back into it and Vanilla Tweaks didn’t show up. I’ve tried fully closing the resource packs folder, relaunching Minecraft, and even deleting and reinstalling the resource packs to no avail.
I followed Vanilla Tweaks’ instructions to the best of my ability (I don’t have much experience with resource packs, this is only my 2nd time installing them), but I might have placed them into my game folder incorrectly, but the installation process was successful 3 or 4 months ago, and the only thing I haven’t tried is opening a world before opening the resource packs menu.
I would be incredibly grateful for some help and patience at your soonest convenience.

Thanks in advance, ScorchedField.
