Xarray's built-in interpolation method does not know how to handle periodic coordinates, which is why you see the blank center line. I would recommend using xESMF, which is an xarray wrapper of some code specifically written to interpolate from one geospatial grid to another, and knows how to handle periodic coordinates (see the periodic flag in the constructor of the Regridder object). It also provides multiple different interpolating methods which, depending on your application, might be more applicable than xarray's options.
