Microsoft Edge Blocks Certain Sites with Access Denied Error

I'm experiencing a weird problem with Microsoft Edge. Certain websites give me an "Access Denied" error, but I can open them just fine in other browsers like Chrome or Firefox.

I've already tried deleting my browsing history and cookies, but the issue remains. The affected websites don't seem to have anything in common.

Can anyone help me figure out what's causing this error and how to resolve it?
