We are sorry about the experience with Bridge and Photoshop 2020.
Would you mind sharing the macOS version you are using? If you are using macOS Catalina, you can add both Photoshop 2020 and Bridge 2020 to the Accessibility list for macOS by going to the System Preferences, then Security and Privacy and then selecting the Privacy Tab. Also, grant permissions to both Bridge and Photoshop under the Files and Folders list. Then restart the computer and check if the issue persists.
