In the mean time, the free version of resolve 21.0.4 will keep working indefinitely.
It doesn't cost Davinci any more dev time to keep it enabled in the free version as the scripting engine is used throughout the app.
And weird to drop support in an odd point release. Usually when features are Studio-only, you'll get a prompt "hey you've reached the limit of the free abilities". Trying already installed scripts after upgrading just failed silently, which was a pain in my butt to debug.
