I'm having the same issue. The extension is having a major memory leak. During calls, the usage goes up to as much as 30GB after which my system goes unresponsive. I have to force quite the extension, to be able to use the camera in calls again. Having to do this during every call is becoming quite annoying. Hoping Fuji is reading along and planning a patch for the leak. Using an X100V on macOS Sequoia, M1 Pro, running Webcam version 2.2.0.
