It appears you have made mistakes in the .desktop file, you have the following line in Exec section as follows; Exec=AppRun %F
It's suppose to be pointing to the executable binary like so; Exec=Discord-Qt because by default .desktop files search in /usr/bin/ for the binary executable. If it's meant to run AppRun then you have to enter the full path to that executable binaries location to tell the system to open from that path.
