I ran the code and initially I ran well, then afterwards the same issue arrived. This all happened after rendering the page flawlessly to what I could see. I did however encounter a style sheet error. As I tried to paste my output of MinGW64, it crashed... If I recall correctly, the errors that @fabricedesre pasted only showed up after closing Servo using the X on Windows 10.

I noticed when running the release, it crashes immediately. The dev mode takes more time and shows more errors than above:
