Even if the zip wasn't corrupted, you wouldn't be able to use the resource pack since it's for 1.16.5 Make sure to let minecraft run with recurrent complex installed atleast one time to let the mod properly generate the folders that are. 1.13 completely changes how the game stores textures, ids and even resource packs so it'd be impossible for you to use the pack unless the author made a version specifically for 1.12.2
Pack should work in current 1.18.x versions, as well as prior versions, java only Mobs (may spawn as with dicks) This pack adds simple shafts to several minecraft mobs, stylised after my creative works on fur affinity
