Garry's Mod Freezes


I have been having this problem since I started playing GMod, where my game would just freeze, then everyone would be teleported, kind of like when you lag. But, I’m not lagging. Anyways, I tried verifying the integrity of the game cache, it keeps telling me that there is 1 file that failed to verify, and I don’t know why it keeps telling me that. I even tried uninstalling GMod by deleting the local contents, and fully uninstalling and removing the GMod folder, none of those fixed my problem.

Any help would be appreciated, as I have been dealing with this for a long time.
