Tick on Samsung Electronics close the details window and restart your Mac as prompted.

Unlock the settings and click on details. Click on go to Security & Privacy settings and under The General tab you will see the text I described earlier. Then reinstall the Samsung Portable SSD utility and you will get the notification saying the extension has been blocked. Follow the guidelines in the medium article to disable the feature mentioned above. Unistall the Samsung Portable SSD utility using the script inside the Application contents. If you miss that at the first installation it will never appear again unless you switch macOs in recovery mode and disable kernel extensions blocking. The first time you are to install the software it prompts you to go to System Preferences > Security & Privacy and under the General tab you are to find a Notification under the "Allow apps downloaded from:" section. This is not a Samsung issue, its a Big Sur issue.
