Firstly, I would like to thank the developers for taking this issue into consideration. It has been really bothering and disheartening since this is actually not allowing me to play the game at all, so it feels really good to see that it has finally been taken up for investigation.
I wish I could lend my PC for this purpose, but I live in a completely different part of the world. Nevertheless, I shall try my best to help, so that this issue can be fixed as fast as possible so that I (and others facing it) may finally play the game.
For your information, I am playing on Windows 10, on the GOG version and on the latest patch (v.1.2.2.0033). Now let me answer the above questions one by one:
In my case, the freeze occurs after the loading screen is finished showing. The screen remains black with only the hand-cursor for an indefinite time. It's not like the other after-loading screen periods where the music briefly pauses and the cursor changes from the hand to the red and then to the yellow one. Here the hand remains indefinitely along with the black screen. At this moment, when I open the Task Manager, the CPU, GPU and Disk Usages for the game's .exe file process is near zero. The only way to exit is to kill the process using task manager. This issue occurs only with this map, and I've not faced anything like this in all the areas that I have access to so far in the game.
I've tried using the console to go to the area directly from the map screen, but the issue still occurs in the same manner.
The issue does occur even on a new game started on the latest patch. I started a new game a few hours ago and speed-ran to the area with Eder and myself, but it's still happening.
Yes, I've experienced this issue on previous patches as well. I don't clearly remember the exact version, but I think it's since v.1.1 at least.
My answer to the last question is indeed the most remarkable thing. The fact is that I have been able to enter the area the very first time I played. I played upto the narration scene with Eothas and decided to take a break. I made a save game, and then attempted to continue playing the very same day, with no updates of any kind in between (neither that of the game, nor any of those pesky Windows updates), and all of a sudden this problem appeared and it continues to persist till date. I simply can't play any further, and I'm sad.
Here's a link to the save game file, dxdiag file and output file when the issue occurs:

I'll try to send the dump file created when this issue occurs, but it's huge (3.83 GB), so it'll probably take me a day or two to upload it to one of my Cloud Drives. (I don't have a super-high-speed internet connection.) I'll update this post with the link to the dump file as soon as I have been able to upload it.
I wish the developers good luck, and eagerly hope that this issue gets fixed soon.
