Hello ryanhardt,
Thanks for clarifying this was on your MacBook and for taking those steps on that device. To continue, we want to provide this article that details the steps to take to add a language: Set audio languages for downloaded items - Apple Support. You would follow this guidance:
- "In the Apple TV app
on your Mac, choose TV > Settings, then click Playback. - Click
at the bottom of the Download Audio Languages list. - Select a preferred language to add from the list, or search for a language using the Search field, then select the search result.
- Click Add.
- When you’re finished, click OK.
To remove a language from the list, select it and click
."
If those are the steps you are taking, let's continue looking into this. Are you able to boot your computer into safe mode? When you do this, you’ll see some unusual behavior from the display; this is to be expected. Booting into safe mode will disable any startup and login items from automatically opening, which can help us to isolate the source of the issue further. Please follow the steps in this article: How to use safe mode on your Mac - Apple Support.
Please test that out for us and let us know if the behavior is present in safe mode also. We hope this helps. Take care.
