We noticed this issue with Gemini 2.5 Pro last Friday in AI Studio; however, it appears to be resolved now.
Could you please try accessing it one more time on your end and let me know if the issue still persists? I’ve attached screenshots showing that Gemini 3 and Gemini 2.5 Pro are currently accessible for me, for your reference.
If the problem continues, please share the screenshots and DM me your project ID.
Thank you!
