What is your issue?

I have an era5 dataset stored in GCS bucket as zarr. It contains 273 weather related variables and 4 dimensions. It's an hourly stored data from 1940 to 2023. When I try to open with ds = xr.open_zarr("gs://gcp-public-data-arco-era5/ar/full_37-1h-0p25deg-chunk-1.zarr-v3") it takes 90 seconds to actually finish the open call. The chunk scheme is { 'time': 1 }.
