Unfortunately your graphic card driver does not support the WebGL driver editor requires.
Please try to upgrade or downgrade your graphic card driver, and search for electron compatibility with your specific graphic card model.
OK, it’s one solution but not the best one.
Which one is better I think is that the Cocos Creator do the extra thing, for example, when my graphics card don’t support WebGL, downgrade to use canvas not let users do the extra stuffs. It’s a bad user experience 
It’s not going to work with only Canvas rendering, sorry.
