@sweetp Since I had not received a notification, I have only discovered your answer today.

It has worked fine. Thank you for helping me to solve the issue!

I am using Big Sur, just upgraded from Catalina, but in recent days I have had the same issue as the one reported by the other user (both on Catalina and on Big Sur). This makes Cookie useless.
 
I have attempted to follow the advice that has helped the other user solve the issue, but:

1. Due to the constant flow of notifications for approving access that block anything else in the app, I am never fast enough for reaching the preferences.

2. In /Library/Containers/ there is nothing such as com.sweetpproductions.CookieApp - I see com.surteesstudios.BartenderWindowHelper followed by com.syniumsoftware.macfamilytree7, but nothing in between. A search on the disk has yielded no such folder.

Maybe it is found elsewhere on Big Sur, or maybe I should remove something else?

A solution would be much appreciated, since I am using your app several times a week
