A lot of users, especially devs, like to use unsaved projects to test things, so this can be a blocker for them.
Steps to reproduce:- Open unsaved project
- Ensure Preferences > General > Paths > Default recording path is set to a relative path
- Try to glue some audio
Expected behavior
Dialog opens informing you no path is set and asks where you want to save render.
Actual behavior
Generic message "Error creating output media" shows and operation fails.
