Well, it's probably because MKL, in MacOS however, when a program tries to use some of the "Intel functions" of the MKL, if the program doesn't properly catch the exception then it just outright crashes. Now you know why so many programs have issues on AMD Hackintoshes: the MKL is used all over the place! This is the basis for issues using a plethora of apps out there including Adobe and Matlab on a Hackintosh.

Just copy and paste these in a terminal

cd /Applications/Discord.app/Contents/MacOS && echo "MKL_DEBUG_CPU_TYPE=5 ./Discord" > discord_

After that you need to open /Applications/Discord.app/Contents/Info.plist with a text editor, find CFBundleExecutable and modify it's value to discord_

After all of this, hopefully Discord stops crashing! 🥲 You can also try this
