You can try this.
Go to Internet Accounts in System Settings. Remove your email Account after clicking on it and click on Delete Account. Then re-add it.
I have been unable to solve the problem this way. But ChatGPT5 asked me to create a smart All Inboxes for any mail in each account. Following the steps advised by ChatGPT5 has now led to full restoration of the previous situation.
Glad you got it working.
