Geminiapi不可用无法换成免费套餐

我最近在使用gemini免费套餐的时候突然发现一直429报错我就到googleaistudio查看发现我的所有项目变成了不可用新建也是一样但我切换了一个账号后发现另一个账号创建的geminiapi没有问题依然是免费套餐

Hi @pc_w
The 429 error means you’ve exceeded the rate limit (RESOURCE_EXHAUSTED). Switching accounts resolved the issue because you were then under the usage limit.

But when I create other apikeys, it still shows that the bill is unavailable.
