Game won't load - Switch

Whenever I try to load into my game on the Switch, it just stays frozen on the screen with the save files, and nothing loads. I do not have any cloud backups available. I’m not sure where to start to try and troubleshoot or fix this without losing the save data.

I tried rebooting the Switch and reinstalling the game, and haven’t had any luck.

Turns out it needed about literally ten minutes to load. After clearing all my decorations from the castle, it’s been to normal.
