It looks like you may be experiencing what happened before in the previous update. I think you will need to unsubscribe to all the arma 3 steam workshop items.

Also you would want to go into your userdata folder in steam: located at <driveletter>:/Program Files (x86)/Steam/Userdata/<steamidnumber>/ and in there delete two folders: UGC & ugcmsgcache.
