After the update, and a bit of confusion with a previous project with a similar name (but totally different location), I’ve found that FD is working again. My apps are running and connecting to the debugger properly. Hooray!
Now I can get back to actual work again.
The downside is that between the excitement of it seeming to fail but actually work and a really tenacious fly, I’m extremely overheated right now and don’t feel up to doing ANYTHING. Not sure what to do with myself now. I’m going to try and cool down by stepping outside for a bit, but I may make ‘fixing FD’ my whole thing for today.
