Getting error on package resolve

Hello,

As of today, I'm getting a wierd error running swift package resolve on windows.

error: 'hermes-swift': target 'xxx' contains a value for disallowed property 'settings'

I checked the package file and module.modulemap for that target and find no references to settings. I've cleaned, restarted etc, but the issue persists.

Any ideas what this error means or where to look next?

edit: the target in question is a library... so its defined on windows as .systemLibrary, and manually linked via linkerSettings (but it doesn't seem to be getting that far in the process...)
