Have you reported the issue to Microsoft and asked them what they changed and why their browser doesn't work since the creators update? You may want to do that as well as letting AMD know about it, which you still have not if you have not submitted an issue report or opened a support ticket. The links for those are in Radeon Settings, the driver download page or contact page on the AMD website. I have no idea what will fix this. I can only tell you I don't use edge ever, and netflix runs fine for me out of chrome and opera. I watch it all the time. My Windows and browsers are fully up to date. My suggestion would be to try another browser until hopefully MS and AMD figure out a fix. This is certainly not the first I have heard of issues like this. They have come and gone several times over the past couple years. One think you could try, not sure if edge allows this, I know the other browsers do, is to turn off hardware acceleration. This may help until there is a driver or software fix.
