I was also facing this issue and found a solution.
Click on the “Investigate Issue” button and take a full-page screenshot. Then share it with Google AI Studio and ask it to identify the issue and help resolve it. I did the same, and now my project is published and working fine.
Please try this method I hope it works for everyone.
In my case, the issue was that the port was set to 8080. I changed it to 3000, updated the Vite file, and adjusted the Express.js (version 5) configuration. After resolving these issues with the help of Google AI Studio, my tool was able to publish and go live again with new features.
Have you enabled billing and accepted the Google Cloud Platform Terms and Services? In the screenshot you shared, I cannot see the Publish button.
Please check whether your billing details are properly connected to the Google Cloud Console.
If you are still facing this issue, please take a screenshot and clearly describe the problem in Google AI Studio and ask for assistance there. They may help resolve the issue.
If the issue is still not resolved by Google AI Studio, you can ask them when they will allow new users to publish their projects.
In my case, I already have an old project that was previously published on Google AI Studio, and I republished it after resolving the issue.
Same issue here, and theres no option to investigate issue. Created a CRM app last week, and I ve been waiting since to publish it. Now the code is too long and can’t even use it on other AI solutions, hahaha
