Problem solved itself. I was able to open it after typing this message. I’m still posting it in case it’s useful as a diagnostic.
What I was doing: I opened two different projects. When I tried to close the first one (the one that wouldn’t open later), there was a delay with the spinning circle. The I closed the second project. I don’t remember if I tried to close the first project again or it just closed itself. When I tried to open the first project again, I got this error. Both from Windows Explorer double-click and from Audacity File Open.
