This probably only applies to a few people, but I tested Edge (Canary) with Open Shell (formally Classic Shell) and the icons looks good, and it works fine. The folder and icons work and look good. Picture attached show’s a demonstration of this.
(I had moved my desktop icons out of picture view, and I have a white background on this computer, thus why my desktop looked bare bones lol. I had also changed the icon form the "E with CAN across it" to just an orange "E", that was just for personal preference/look and has nothing to do with Edge or Open Shell.) :)
