Thank you for addressing this issue, @jrbourbeau!
It appears that the failing tests are unrelated to your changes

This PR updates how we construct the
HighLevelGraphinsubset_dataset_to_block. Currently we create aHighLevelGraphand then manually add a few new layers, which aredicts, directly tohlg.layers.xarray/xarray/core/parallel.py
Lines 537 to 546 in eec2b59
However since (in more recent versions of Dask)
HighLevelGraphlayers are expected to beLayerclass instances this can result in unexpected errors (xref #5077 (comment)). Instead of manually adding new layers tohlg.layers, this PR proposes we create a newHighLevelGraphaltogether to ensure thathlg.layerswon't contain any rawdictlayers.
