I want to use the Quest LIV watch mode again. Unfortunately, it's been removed. Here's how to fix that.
1. Download LIV on Steam if you haven't already.
2. Open the [Steam Console](steam://nav/console).
3. Run the following command: `download_depot 755540 755541 4753480397245922396`.
4. Wait until the download is finished and then open the folder it gives you.
5. Copy the `depot_755541` folder into your standard `steamapps/common` folder (use the Steam client to open local files for LIV then go back one folder).
6. Rename your normal `LIV` folder to `LIV_old` or something like that, then rename the `depot_755541` folder to `LIV`.
7. Launch as normal.
Oh, and, disable auto-updates on Steam for LIV too. That'll prevent it from updating again.
