What Happens

WHAT I HAVE TRIED ALREADY
- I followed the recommended troubleshooting steps, but the issue persists. https://www.epicgames.com/help/en-US/epic-games-store-c-202300000001639/error-messages-c-202300000001736/is-0007-or-is-0009-manifest-failed-to-load-a202300000013120
- I fully uninstalled the Epic Games Launcher and removed all remaining launcher-related folders to ensure a clean reinstall. After reinstalling the launcher, the issue still persists, and downloads continue to fail.
- Lastly, I have never encountered this issue prior to now.
