@ZipBrandon , for me - on the other hand, I had opposite situation - I got a whole form state from whatch subscription and stored it in redux toolkit store, which under the hood looks like “proxified” this object using immer perhaps. And still as for you I’ve resolved it by doing deepClone before use form state elsewhere.

I also ran into this problem when setting form value from redux-toolkit selector, I fixed it by using deep clone setValue('arrayField', JSON.parse(JSON.stringify(formValue))).
