@ACHMartin the issue is when you do newds['z'] = stacked.z. In the last versions of Xarray multi-index levels have each their own (real) coordinates, for consistency and clarity we soon won't support assigning a multi-index to a single coordinate of a Dataset / DataArray like that.

I think that in other places we still do support it with a deprecation notice, but apparently in your example this is not the case. unstack doesn't work because the multi-index(es) and the coordinates of newds are not consistent.

I don't know exactly what is your real problem, but from now on you should avoid implicitly assign a multi-index with xr_obj["my_coord"] = ... or xr_obj.assign(my_coord=...). Instead you should re-create the multi-index, e.g., in your minimal example newds = newds.set_index(z=["across", "along"]).
