Is your feature request related to a problem?

Related to:

xarray.open_mfdataset() + .load(scheduler="sync") hang with some large E3SM v3 datasets. The root cause was identified as being a regression between dask=2024.11.2 and dask=2024.12.0.

Describe the solution you'd like

  • Validate dask=2025.1.0 update fixes performance issue using MVCE from here
  • Perform complete v3 run with dask=2025.1.0
  • Update dask constraint to dask !=2024.12.0,!=2024.12.1 in dev.yml, ci.yml and pyproject.toml
  • Inform @xylar on status and if E3SM Unified can update its constraint

Describe alternatives you've considered
