Artifact share dialog blocks public sharing with unclear error; version dropdown unresponsive

When trying to share a Claude Code artifact publicly (General access: Only you → Anyone with the link), I get this error:

"This version can't be shared publicly. Publish a new version or change the shared version, then try again."

Steps to reproduce:

1. Published an HTML artifact via the Artifact tool in a Claude Code session
2. Opened the artifact URL, clicked Share
3. Tried to change General access from "Only you" to a public option
4. Got the error above

I then had Claude republish the artifact (same file path, new version) hoping it would resolve a stale pointer — same error persisted.

The suggested workaround in the error message ("change the shared version") doesn't work either — the "Shared version: Latest" dropdown does not open/respond when clicked.

Artifact URL: https://claude.ai/code/artifact/bacf631b-d3ec-471a-a3f4-529c62e7f274

Expected: either the share toggle works, or the version dropdown is clickable so I can pick a specific version to share instead of "Latest".
