I'm not sure if this is a bug with Construct 3 itself, or something else has gone wrong, so I hope this is the best place to post this!
I am getting an error repeatedly whenever I try to preview the game.
When previewing, the preview opens up (I've tried this as both browser and popup window and the same thing happens), but the project file crashes with the "oops something went wrong" message and I have to restart the session.
This happens whether Construct 3 is in browser or offline app, and it happens with a clean project file (no assets etc) too.
This is a copy of the error report - any ideas at what could be causing this?
