Dear @Michelle T,
I completely understand how confusing this can be, especially since it was working before and now the background doesn’t appear even after you select one.
In this case, it might be caused by camera permissions being reset, especially after a macOS update. If the app does not have full access to your camera, background effects may not apply even though they appear selectable.
Step 1: Go to System Settings > then Privacy & Security > and open Camera. Ensure that the app you are using (such as Teams or Zoom) is enabled. If it is already enabled, try turning it off and back on, then fully quit the app and reopen it. For reference: Control access to the camera on Mac

Step 2: If the issue persists, it can sometimes be caused by a temporary app glitch or corrupted cache. I recommend you tried clear the Teams app cache on Mac. For more information and instruction, please refer to Clear the cache in Teams for macOS
Step 3: Please try updating the app to the latest version or reinstalling it can also help.
If the issue still persists, to better understand what’s happening and guide you more precisely, could you please help me with a few details?
- Does the issue happen in all meetings or only in a specific meeting or app?
- When you select a background, what do you see on your screen? For example, does nothing change at all, does it show a different background, or do you see a blank/solid color instead?
- Additionally, could you confirm if this behavior occurs in other apps as well?
- If possible, please share a screenshot when selecting the background.
