If you're seriously gonna sit here and disagree with literally every other cemu user and the official setup guide written by the mod of r/cemu, then you're either a troll or ignorant or both. Serfrost did a good job explaining this in the official setup guide for cemu: If the cache is built on BOTW version 1.4.0 or above ONLY, then there aren't more than 9600 shaders. Or I guess you could drop back to cemu 1.7.5.
You need to find an updated cache if one exists or just play the game and build your own.
So the only way to have a cache without those old invalid shaders that aren't used anymore is to build the cache fresh on 1.4.0 or above. Then it definitely is an old cache and not compatible with cemu 1.8.0. So any cache built on versions before 1.4.0 have old shaders that are no longer used on 1.4.0 and above and are therefore invalid and just wasting RAM. If you were around for the 1.4.0 update for BOTW, you'd know that it invalidated shadercaches as explained here:
