Stage Striking Layout No Longer Updates

When using layout/stage_strike/index.html or layout/stage_strike/index_autohide.html the stage striking doesn't update, and TSH has this error:

On index.html, in the console:

Start with layout/stage_strike/index.html, layout/stage_strike/index_autohide.html, and index.js lines 96-103, then trace the state update data used by Update. Check src/TournamentDataProvider/StartGGDataProvider.py lines 419 and 865 and src/TSHGameAssetManager.py line 1485 to determine why stages and game data are undefined. Done means both layouts update stage striking without the reported console or TSH errors.
