Seems like boost gets downgraded which also downgrades pyarrow. I'm not sure how to debug a dependency issue like this, and I don't have a windows box to reproduce it.

Asking help from @conda-forge/core

[xhochy]

@Ingvar-Y Is this still a problem? There were a lot of blas fixes in the last month so this should be solved.

[Ingvar-Y]

@xhochy I don't have this issue since updating conda to 4.7.x

[xhochy]

Nice to hear, closing then.
