How did you install UXarray?

What happened?

Uxarray constructors are now failing with TypeError('Passing a Dataset as data_varsto the Dataset constructor is not supported. Useds.copy() to create a copy of a Dataset.') . Due to pydata/xarray#11139 in https://github.com/pydata/xarray/releases/tag/v2026.04.0

What did you expect to happen?

No failures

Can you provide a MCVE to repoduce the bug?

You can use the test suite in this project

Thanks for reporting, @VeckoTheGecko ! We'll be looking into this right away (we'd already found this in the upstream CI of another tool of ours but missed that xarray would release that soon)

Haven't tested it, but I was thinking you can probably call ds.to_dict() in UxDataset.init before passing it through to xr.Dataset.init.

That's probably the most straightforward fix
