corrupted update files

Hey y'all, since the second patch has been released, i have been unable to update my game it's either been saying update failed or corrupt update files and i've followed a few fixes and none of them have worked the ones i've tried are as follow.

Clear Cache.

Checked to see if my RAM was the problem.

Deleted all but two files from my steam folder.

Tried verifiying integreity of game files.
