Kicked out of Game when firing weapons?

I have uninstalled and re-installed Epic Games Launcher several times. If I get in a firefight where firing too many weapons I get kicked out of the game… usually no crash report just kicked out of the game and have to re-launch. However, just got a crash report… see below. I have on lowest graphic settings & display. Why does this keep happening?
