Valorant freezes my computer

so I recently (about two or three weeks now) encountered this issue, while having discord and valorant running both or trying to open discord while valorant is running, my computer freezes and the only thing I can do is to turn it off by the power button. nothing else works, I want to know if there's anything I can do to fix this? it's not a big deal, but if anyone provides a fix I appreciate it.
