Edge doesn't load specific sites but downloads instead

So I've been having this problem for about a month now where a few sites, like WindowsCentral, won't load in Edge. Instead, Edge downloads a .htm file. These websites load perfectly fine in IE. I have this problem on both my laptop (15063) and my work PC (14393) but not on mobile (14393). Switching off my add blocker doesn't help (uBlock Origin).

Any thoughts on how to fix this would be really appreciated!
