Daz Studio Crashing at start Up

Sestifer

Hi,
I've stopped working with DAZ Studio4 3 or 4 years ago. I have been using it on my Mac Pro (2012) with no problem until that.
I wanted to use it again 2 days ago and tried my old installation. It crashed at startup.
As I have moved to High Sierra 2 or 3 years ago, I thought there was a compatibility issue with Mac OS X. I then installed the new Daz Studio 4.12 and same thing happened : crash at startup.
I looked on the internet and on this forum and it seems there are some other people with the same problem. None of the tricks I've read solved my issue.

I though it could come from my Nvidia driver. I reverted to my previous video card which was provided with my mac (AMD 5770) but Daz Studio still doesn't work. It seems the problem is not driver related.
I tried to move back to Studio 4.8 (I've kept an archive copy), but it still crashes.

I have these 2 error logs (attached file).

I managed to change rights on the designated folders. The last 2 errors don't show anymore... But Daz still crashes at start up.
Is somebody having an idea on what's going wrong and how to solve it ? Any suggestion would be grately appreciated.
Thank you.
