Hey guys, everytime I open a new firefox browser, it'll ask if I want to change it to my default browser and bring up the default programs window for my windows 10. However, every time I try to change the default browser from Microsoft Edge to Firefox, the window will pause for a bit, then just close. This never really bothered me too much, but now I'm trying to download something from Microsoft's website, and this problem is becoming the reason why I can't download it. Why is the window just pausing for a second then closing? It's like it doesn't know how to respond to my choosing firefox and just crashes.

PS. If it helps, it seems that if I try to change it to ANY other browser but Microsoft Edge, it closes the window.
