I am actually observing this right now everyday, pretty confident in what it is
I am also the one who found out that it was the new noblock update that lagged the server back a few years ago and instead of going back to old noblock and fix it he decided to just make an "unstuck all" command. which is fine i guess (its in our old dms)
So since we got a server restart yesterday (crashed the server and we reset more or less) now if anyone experiences any of these freezes the next days from now and out please make a comment.
If my estimates are accurate its probably gonna be like 5-10 days+ until people starts crashing again and that confirms my theory, so far all we (i) and you have to do is observe and see if it happens again since the (server restart last night)

@Paw that video I posted, that is the game you crashed in, as you said 5 min ago that is the exact same map, round, that we played and you crashed in ^^
