I read the whole thread up to the point I am commenting. So who are you letting in your home that could be doing this? That’s the first question I would ask myself.
Did you throw away the bag so you cannot recover it?If not, I would shut that nonsense down.If you can,get the bag back. DO NOT touch the contents. Use it as a link to the original caster to return to sender. I would do this on Wednesday, hour of Mars, evening time. Then seal the bag in a jar full of earth and cast the sealed jar into water for disposal. I would follow through with personal cleansing and uncrossing on yourself followed by a complete cleansing/banishing of your property, sacred space included. Consecrate the areas afterwards.
And for the love of self try to figure out who put it there. From chains to a bag with death hex materials it sounds like someone tried to bind you, failed and is trying to step things up. If you are willing, maybe evoke Focalor to protect you, lethally.
