Discord is failing on PC, yes? It works fine on your phone? I have a different problem, Discord never crashes, but I often close it manually since my machine will reboot if I have to many applications running simultaneously on Windows. Memtest didn't turn anything up, so I'm going to reinstall Windows and see if that works. Might be a solution for you too?
Before doing that though, did you try booting Windows in safe mode with networking and loading Discord there? I assume some kind of conflict with another program, so loading your applications one by one after Discord might identify the culprit.
