[CRASH] "Crash Dump" stops me from entering matches

I've been playing for over a year on this exact same Laptop the entire time and this is the first time this message has come up preventing me from even entering a game.

Step1: Enter ARAM Step2: Game Countdown winds down Step3: End of countdown and client disappears as normal Step4: Error message comes up and nothing further can be done to enter the match Step5: Reopen Client, see "Reconnect" button, click it Step6: Error message comes up again as it did before

I cannot enter any match. I have not downloaded anything new. I have initiated a FULL REPAIR but nothing happened.

Attached is the "Crash Dump" file. Thanks
