I'm getting the following error in my console:

It does not happen in the sandbox vault, and I've turned off all plugins and restarted my vault, still not working.

Here are my other plugins, though not all of them are typically in use.

Let me know how I can help track this bug down.

Sorry it's misbehaving. The fact that it does works properly in a sandbox vault makes me think there's some interaction happening with one or more of the plugins installed. A few questions:

1. What version of Obsidian are you running?
2. Does this happen when you try to perform a specific action/sequence of actions, or, every time you try to use the switcher? I'm going to guess every time, but if that's not the case, then it may be useful clue.
3. Are there any other errors reported in the console beside what you've already shared when it happens?
4. Do any of those plugins try to "manage", "augment", or otherwise change Obsidian behavior around recently used files? for example, I know there was a plugin that tried to keep a longer list of recently used files (can't remember the name of it) or something like that.

You might try bisecting your plugins. Create a new vault, install the switcher and confirm it works, then install only half of all your plugins and enable them. See if the error occurs after that, if so, then the interaction is with one or more of those plugins. If it doesn't happen then try the same with the other half of your plugins and try again.
