Issue with schema and effect type preservation

export MyType = typeof MyTypeSchema.type
export async function test(): promise <{ ok: true, value: MyType } | { ok: false} >{
const res = Effect.runPromseExit(myEffect)
 if (res.tag === 'success:) {
return {ok: true, value: res.value}
}
return { ok: false }
}

test.then((res) => if (res.ok) {
    // Here I want res.value to keep types but it is Types.simplify<any>
})
