Follow these steps:
Go to the bottom of the visualization and find your name toward the right. Click on the little downward triangle and choose Sign Out. Then, go to File and try Save to Tableau Public again. You might have to try this a few times, because this issue can happen intermittently.
Go to the top menu and select Help > Settings & Performance > and select Clear Saved Server Sign-ins.
Use Save to Tableau Public As and choose a different file name.
Copy the workbook sheets to a new workbook and try saving that one.
