I stumble across the same issue trying to convert a 5000 column dataframe to xarray (it was never going to happen...).
I found a workaround and I am posting the test below. Hope it helps.

```python
import xarray as xr
import pandas as pd
import numpy as np

xr.__version__

    '0.15.1'

pd.__version__

    '1.0.5'

df = pd.DataFrame(np.random.randn(200, 500))

%%time
one = df.to_xarray()

    CPU times: user 29.6 s, sys: 60.4 ms, total: 29.6 s
    Wall time: 29.7 s

%%time
dic={}
for name in df.columns:
    dic.update({name:(['index'],df[name].values)})

two = xr.Dataset(dic, coords={'index': ('index', df.index.values)})         

    CPU times: user 17.6 ms, sys: 158 µs, total: 17.8 ms
    Wall time: 17.8 ms

one.equals(two)

    True
