That implies you don't have a valid cache/stills path.
In Resolve Preferences - System - Media Storage, the first location in the Media Storage area is the default stills and cache path. Make sure that's a valid path that Resolve is allowed to write to.
BTW: Are you using Resolve from the BMD web site, or from the Apple App Store? Edit: never mind! Resolve 15 beta would not be from the App Store. duh, long day.
