I am running into this error all the time when I load a design. The UI pops up, shows the error, auto-refreshes, shows the error again, and repeats. It does not seem to happen when offline, just when online. It happens on lots of different designs, including one I did today that was just 3 rectangles created in inkscape.
This is seriously compromising my ability to make cuts; it happens repeatedly when I’m trying to make any changes. How can I track down what is going on?
