Fortnite download loop

Hello, recently I have become in love with Fortnite and it all wokred perfectly fine until out of nowhere, one day it wouldnt work anymore. Everytime I launched the game it would crash with the message “You do not have any debugging symbols required to display the callstack for this crash”. The problem got worse and even started crashing my entire PC when I tried to have the launcher open. I even went as far to deleting Fortnite, then a new problem popped up. The download would be infinitely downloading. It would take an hour or two to hit 100% but then restart at 0%. It would just loop and loop forever. I usually just keep it downloading just in case but the launcher still seems to crash my PC giving me a blue screen forcing me to restart it. It has gotten to a point that has really annoyed me and I would really like some help before the next season starts because I plan on actually spending money in this.
