Issue

Thanks for re-enabling windows for dftd3! This more of a public service announcement than a bug report. It looks like the latest d3 (python or simple-dftd3) and d4 c-f packages cannot be installed together on windows. Below is a sample env.

I suspect that d3 is built to current standards, and it is psi4 and the other packages (win disabled on d4, so that is an old build) are the ones that need to catch up on c-f windows build conditions, so this is just posting info.

This is part of the migration running for m2w64-ucrt. Packages build before the migration are unfortunately not compatible with packages build after the migration.
