AI Studio Issue: No Token Count & "Run" Button Disabled in Old Chats

Ah… I am having the same problem and so it’ s likely a broader issue and not a setting (or some strange token issue). I posted the following in the Gemini forum and someone suggested I post it this forum. Sounds like this is a problem that started a couple of days ago and affecting more than just me! I have some old sessions that still work. See my scenario below and let me know if there is a pattern.

I’m a Google AI Pro subscriber and am experiencing a recent issue in AI Studio where the Run button and Ctrl + Enter functionality have been disabled in 3 out of my 9 active sessions.

Details

  • The affected sessions are part of a 4-part series following a consistent naming convention (e.g., Phase 1, Phase 2, Phase 3, etc.).

  • The most recent session in the series (Phase 3) still functions normally.

  • All unrelated sessions outside of this series are also working as expected.

  • Token usage is well below the 1 million-token limit:

    • Session 1: ~600 k tokens

    • Session 2: ~500 k tokens

    • Session 3: ~33 k tokens

Troubleshooting Steps Attempted

  • Cleared browser cache and cookies

  • Tried multiple browsers (Chrome, Edge)

  • Tested in Incognito/Private mode

  • Submitted feedback through the in-app feedback option (no response yet)

Summary

The issue appears to be isolated to a subset of related sessions. It’s unclear whether this is a token-count, naming convention, or session-state issue.

Has anyone else encountered similar behavior, or does anyone know of a workaround or method to re-enable prompt execution in affected sessions?

Thank you in advance for any guidance.
