Empty Exception for each open_rasterio call

[djmallum]

I searched and was unable to find anyone else reporting this issue.

Code Sample

Here is my minimum working example

import numpy as np
import xarray as xr
import rioxarray as rio

y = np.linspace(40, 45, 10)
x = np.linspace(-75, -70, 10)

da = xr.DataArray(
    np.full((10, 10), np.nan),
    dims=['y', 'x'],
    coords={'y': y, 'x': x}
)

da.rio.write_crs('EPSG:4326') \
   .rio.set_spatial_dims(x_dim='x', y_dim='y') \
   .rio.to_raster('geo_grid.tif')

for i in range(1,100):
    loaded = rio.open_rasterio('geo_grid.tif')

Problem description

So in this case, after any exceptions (in the above there are none) or errors, 100 copies of the following are printed:

Error in sys.excepthook:

Original exception was:

Exactly as is, no additional detail. Whitespace is consistent.

Expected Output

Nothing.
