Thanks for reporting this, @techieforfun!

This seems to be the same problem as https://github.com/hashicorp/terraform/issues/33977, which already has a fix staged for inclusion in the forthcoming v1.6.1 release, and so I'm going to close this.

As you noticed, this is a new problem in v1.6.0 so I suggest remaining on the latest v1.5.x patch release for the moment and we'll be publishing v1.6.1 soon once a few other separate fixes are merged.
