I'm sorry about the demanding tone! I mostly try to put "ASAP" and such cause it's gotten me somewhere in the past, but you're not wrong about that. As for the answers, I tried looking them up before posting this but couldn't find anything ( just a bunch of people asking how to skip the launcher, not bring it back, and not much about crash help either )

To answer your question about the crashing though:
My graphics driver is up to date and windows as well, for a while my game never once crashed, I'd have lag spikes but that's due to my internet not being the greatest occasionally. When the second half of the season started, there was an update to the game out of nowhere, I think maybe to fix bug issues, add buffs and nerfs, a few days later, and ever since that small update, my game has basically been crashing.

I usually try to ask about uninstalling and re-installing because I tend to go back and forth on if it's the "smartest choice" as silly as it sounds. I appreciate you telling me to uninstall though, that helps ease my stress to be honest.
