Looks like the save file (save.json) couldn’t be loaded but I have no idea why. Normally if the file isn’t readable the game will create a new one. The only explanation I have is that the contents of the file are somehow corrupted. Can you try removing the file in the net.monometric.sketch-share-solve folder and see if it loads?
