Hi, this is a macOS privacy prompt, not a Bridge error. Bridge is a file browser, so at launch it can touch files and folders that belong to other apps, and macOS then asks for permission — Apple describes this kind of access under Full Disk Access as access to data from other apps.
To stop it coming back at every start-up, set the permission once: Apple menu > System Settings > Privacy & Security > Full Disk Access, then add Adobe Bridge 2026 (or turn it on if it is already listed), and quit and relaunch Bridge. Clicking Allow in the pop-up should do the same, but setting it there is the reliable fix if the prompt keeps repeating.
If you choose Don't Allow instead, expect the prompt — and limited access to some folders — to keep returning.
