Firewall/Game Crashing Bug!!!!

I created a post on 12/18/2014 about 'Firewall' game crashing issues which subsequently lead to the 'Calculating Differences' screen of death and was able to fix the 'Calculating Differences' screen of death issue (Redownloading Windows Updates - 4 hours worth -) and was able to get back to playing League of Legends (Draft Pick Normals, Ranked, ARAM, LOPK).

However, when I queued up in Team Builder, waited an accumulative 10 minutes for a match (even though approximation was 1:12), and got ready to play - I got the black screen of LoL crashing...again.

I theorize that either 'Team Builder' or selecting Riven, Ziggs, or another champ in 'Team Builder' may the root cause of mine, and other's, problems. I also hypothesize that a corrupted 'Team Builder' file may be the reason why, after alleviating the patching problem of 'Calculating Differences', the game continues to crash.

I have yet to try to relaunch LoL but, if my theory and hypothesis' are supported, I should expect to run into another 'Calculating Differences' screen of death again (due to the LoL Patcher trying to find the corrupted file which probably seems normal to the system but not normal enough to promote efficient patching).

-Will update upon testing that theory-

Evidence to support my theory:

1.) Every other game mode works fine and has caused no issues; 2.) Team Builder's wait time is astronomically long regardless of approximation; 3.) The only two times my game has crashed in the past 24 hours is when playing Team Builder; 4.) Each time I tried taking Riven into the match and never even got to the Champion loading screen after 'Prepare Yourselves for Battle!' message; 5.) Noticed that when I played Riven top 2 days ago, mid Ziggs was AFK the entire game (Possibly due to the same issue).

Will spend the rest of this morning (5:15 am as I write this post) testing the game and seeing what meaningful things I can pass along to Riot in hopes that they take notice of this issue and try to find the best possible solution.

Update:

Relaunched the game and was able to connect to the match I was d/c'd from. However, I was behind 13 levels and was able to build tanky and help our team win the game with a 5/8/14 ratio. However, when trying to play another game, TB wouldn't even launch (no permissions). I feel that TB may be broken.
