League MS High

Since the patch, my MS has been jumping from 30 to 400. It seems to only be League of legends which this problem occurs. Pubg has no issues. I've done speed tests and everything is fine and my download speeds are consistent. I've turned the firewall off and on and still have the issue. I've changed my settings in game and this hasnt fixed anything. I've uninstalled and reinstalled and did a repair and nothing has changed. My internet is fine. Its just league where the MS is an issue.
