When I'm in a certain directory, not this directory, because I couldn't get it to run, when I'm in a different directory that was working with Claude Code, I made a change with cursor or something into a file and somehow it broke it so Claude won't run in that directory. Tried reinstalling Claude, using different js runtimes, and a whole bunch of things, tried deleting recent files. I had to switch to a different directory in order to be able to launch this so I can file this bug report. In fact, while I was trying to recreate this bug report, it stopped working in a second directory that had been working, so I then had to use it in a third directory just to be able to launch Claude to send this bug report.
