I was able to recover the Manager.app v 20.2.34 file and the .manager files by Time Machine and it is now working normally. I recently lost all my Manager files by accident and then managed to restore them in the past, around March / 2020. I believe that there may be remaining files in the Manager folder, because when I updated the app today, duplicate business files were created, such as “Business (2)” for example. I think I should fix the database for my Manager. What do you think? I was taking a look at this forum thread (All business Gone - #9 by AAmey) and I think it might apply to me.
