Starting with OS Catalina, Apple tightened app permissions. Something that might also help your situation is to delete anything Zwift-related on your hard drive, and start a fresh install.
- Using Mac Finder, search for “Zwift.”
- Delete all the folders and files that came up in search. This step removes all the old stuff, and any potential conflicts that cause the game not to launch corectly.
- Download and install the latest Zwift game app from Download Zwift on iOS, MAC, PC, or Android Devices | Zwift
- VERY IMPORTANT: during installation, you’ll be prompted to allow Zwift access permissions. Should be for the Documents folder specifically, but if others come up, say yes. I’m on Windows personally, so I can’t say for sure what Big Sur asks for.
Would you try that and let us know if that solved your issue?
