Polaric Void and Kirac Vault crash

I haven't had a problem going into the quest related Polaric Void (the first one you get that's green) in previous leagues. This league, I just got the invitation, put it into my map device and the portals show up. When I click the portal, the game crashes. I relaunch the game and try again, same result. I also think that whenever I go to a hideout with those portals open, I also crash as soon as I try to visit the hideout.

Also, every since I reached the 6th reward for Kirac's Vault, I crash as soon as I get close to the vault door. I can go into the 5th reward room and it triggers the vault door for the 6th room, but when I go to the 6th room (even if I just click slowly and inch my way over), as soon as I get to the opening of the vault door, I crash.

I have changed multiple settings in game and out. I've updated my drivers and still can't go in either area. I haven't progressed the game further to see if there are infact other areas that I have the same experience with, yet, so there may still be more things that cause me to crash.

Other than those two areas, so far my game has been running very smooth. I don't crash randomly, or in any other areas that I have progressed to so far.

I play the game through the Steam client and have disabled item filters, Steam Overlay (and other overlays), closed all other applications, and tried launching it from the .exe as well.

Please, if I could have some info or if anyone can reply some things they have done that could help. Maybe there's a setting in game that I don't know about that's enabled/disabled.

Super glad to see I got zero replies and zero help for my issue :P

As an update for people looking for a possible fix, I uninstalled and reinstalled the game again, and now I don't seem to be having the issues I had above. There is still a small lag spike that happens at the kirac vault when I pass the 6th vault room, but I don't disconnect at least. The polaric invitation went fine without any lag.
