I have had similar issues but my crashes cause my computer to full restart. This is the only game I have this issue with... I can't even make it past the match loading lobby.
I am having an issue when I get into the game where I can't ready up because "Client is out of date" and it is asking for me to update. The only problem is that steam isn't showing an update. I tried to uninstall and reinstall. That didn't work.
Any help would be nice! :)
