js error in Project Tiny scenes

After working on a scene in Project Tiny for a bit, I am now getting the following error:

Exception: Tiny: fs.js:646
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
^

When I click play, the editor will go into play mode, but no actual game window opens in my browser. This problem occurs even in TinySample scenes, so it doesn't appear to be a problem specific to my scene. I tried deleting and reimporting Project Tiny to no avail. I am using 2018.3.0b12. Any tips?
