Attempting to open the Sequencer in a Track with a deleted file throws an error/white screen

[brandongregoryscott]

Steps to reproduce:

1. Create a new Track with at least one step.
2. Save the project.
3. Go to the library and delete the file associated with that step.
4. Go back to the workstation and attempt to open the Sequencer for the Track Section that had the step.

The screen will go white and errors in the console will read:

react-dom.production.min.js:127 Uncaught TypeError: Cannot read properties of undefined (reading 'name')

Not sure what the best course of action is here (you should realistically be able to replace the steps with a separate file/sample), but it at least shouldn't blow up if the file can't be found!
