GCP service account is limited to access Google Play developer account

[wyz]

I have a GCP service account function normally since 2021. Other developer account in Google Play can invite my service account to access their financial report and other info. However, recently when new developer tried to invite my service account, they receive message "此服务账号已经有权访问其他10个开发者账号，已达到上限", which means "this service account already has access to other 10 developer accounts, which already reaches upper limit". But my service accounts already have access to more than 50 accounts, and this error only occur recently with new developer account. Anybody has ideas what's the issue?
