The main cause for Discord to crash is the game overlay that it has. If the overlay is not the problem, you should reinstall Discord to see if the issue is caused by some corrupted files instead.  Here are the steps you need to follow to fix the Valorant error 404 when using Discord as the main overlay app:

1. Turn off the Game Overlay inside Discord

2. Reinstall Discord

Another reason that might cause the Valorant error 404 could be some corrupted files that are affecting Discord.
