I was trying to get Xdebug working with DDEV and VSCODE. Finally, I decided to try to update DDEV to the latest version. I did that, and somehow Xdebug started working, which was great. Then I shut everything down and took a break.
When I started everything up again, I found that the existing projects wouldn't start anymore. That is, ddev start just hung. But I found that when I created a new project, it acted normally. I tried various deleting strategies (ddev delete), but that wasn't enough. I did find that deleting the entire .ddev directory and reconfiguring made it possible to create a new project for a folder, but that seemed a bit drastic.
So, I'm guessing that somehow, that updating got something out of sync in existing projects.
Any pointers to what I might do to investigate or fix those existing projects so that they can start?
