Unable to launch Fortnite

Development Platform & Builds

First, my Epic Games Launcher failed to launch whenever I would use my GPU to run it. I switched to my CPU, and now it’s running fine.

Now, whenever I try to launch Fortnite, I get this error: You do not have any debugging symbols required to display the callstack for this crash."

I tried copying it, and it gave me this: "Fatal error: [File:Unknown] [Line: 826]
Rendering thread exception:
Fatal error: [File:Unknown] [Line: 251]

I have tried:
Uninstalling and reinstalling my card drivers
Uninstalling and reinstalling the Epic Games launcher
Uninstalling and reinstalling Fortnite
Installing Unreal Engine for the editor symbols for debugging
Running with CPU
Running with GPU

Nothing has worked. I am still getting the same error.

I was playing fine yesterday, and didn’t shut anything down unusually. I haven’t downloaded anything new or updated anything.

Any help would be great, thank you.
