Gmod Startup Crash

Whenever I launch Gmod it starts loading then I get the error ‘!SteamRemoteStorage’ and then it crashes to the desktop. I’ve reinstalled Gmod twice, verified integrity of game cache, deleted all addons, and defragged the game cache. It’s only done this after the Gmod 13 update. Before the update it gave me the error ‘[Steam] SteamApps() Is NULL’. Any ideas on how to fix this?
