Went into VSCode today to deploy a project that's been waiting on user approval testing and feedback. Right-clicked one of my custom transaction body field XMLs to update it from the sandbox environment where I developed it, and the SDF extension throws an error saying

Freight Booking: Address already in use: bind

I've never gotten this error before, and I'm really not sure what it means. Where should I start to find out? I have a custom form in the project named "Freight Booking" by the way, but nothing changed on it between last time this worked and this time when it throws the error instead, and I'm not updating that component directly. The folder my project is in is also named "Freight Booking". Ah, I see this "bind" error always happens at the same time as this other one:

Freight Booking: The authorization credentials associated with NSajm_SB auhtid are no longer valid. Starting the browser-based authentication for refreshing them.

So, to fix this I decided to create a new browser-based authentication, but then I get the same error (in the Output pane this time). UPDATE: Fixed by the good ol' Reset The Computer trick.
