I am having exactly the same problem. After this maintenance, I was able to play for a couple hours, but not to join a job. Then, everytime I tried entering my garage or my apartment, the game would froze with the camera focused on the building, or on the garage gate, depending on where I was trying to have access.
Noticing that, I changed my respawn location to my apartment, and tried to go to a new session. It worked. I spawned on my apartment. But there was no more exit door (the one that you use to leave your apartment or go to your garage). Just gone. I could even go through the hole on the wall, walk by the corridor and go into the elevator that, obviously, wouldn't move.
And this is where it ended. Now, everytime I try to connect to GTA Online, it will load forever, and then time out. It won't connect for sh*t. My other character, that is lvl 6 (95lvls below my first character) connects fine. So I don't know what the f*ck is going on. And there is nothing I am aware I can do about it.
Edit: Well, I figured out a temporary solution. And it really is temporary.
I went to GTA V singleplayer and asked for a friend to invite me to a simple job like golf. Then, after accepting it, I was able to join the lobby, because it made me spawn in front of the golf field, and not inside my f*cked up apartment. I played 1 hole, and after the job was finished, I respawned in front of the golf field. Done that, I changed my respawn location to "last location" instead of "f*cked up property", and now I can join sessions again.
But, I can't host jobs, I can't join jobs (like missions, dms and races), I can't access my f*cking property/garage, I can't even use the Content Creator because it will freeze too. In other words, I can't do sh*t after this maintenance. Well, at least I can walk with my virtual dog in the freemode.
Oh yeah, they wiped out all the f*cking animals in GTA Online too.
