Tbh there's probably just something wrong on my end.(Game freeze)

Recently my games have just frozen for no reason at random points into the game and the most annoying part about these freezes is that they're permanent unless I can get task manager open and close it (I think).Like, I'm just playing and then I hear that windows noise sorta alerting me that something has gone wrong and then my game just stops, I can still move my mouse tho and I can still do stuff on my other monitor.No sort of bug splat program comes up either(The one with heimer and a hard hat).

So could anyone tell me if They have had something like this go wrong.

Also I cant close it with task manager because it opens under the league game, of which I cant minimize. (-3-)
