A little tough to see everything in your box, but here is what I’m thinking. How many neutral bundles are in there? It looks to me like there is just one, but you have 2 circuits in that box. If that’s the case, separate the neutrals into 2 bundles, one for each circuit, as they shouldn’t be blended.
Neutrals from 2 circuits connected together are notorious for tripping AFCI’s. I don’t know why the Inovelli switch would make a difference, but try separating them (which they should be anyway) and see what happens.
