It was. If you go through the OP thread, one of the responses is a picture of the dialog window that this user clicked through saying, "these changes will be IRREVERSIBLE".

The OP was just playing with a new kind of fire (VSCodes Git/source control panel) that they didn't understand, and they got burned.

We all gotta get burnt at least once, but it normally turns us into better devs in the end. I would bet money that this person uses source control now, as long as they are still coding.
