Cross origin behaviour changes in the browser between versions. You could try with different web browsers and see if they allow these images to be loaded. Onether thing that could have changed is what images you are trying to load. The sites you are fetching them from might not use proper CORS.
I've tried this with an image of my own, from my phone camera, that I put in resources/public. I get the cross-origin error in Safari/MacOS. In Chrome, I don't get the same message, but it also fails and I see this in the javascript console:
