Network crash 4008 for each mission (Free, France)

Warhammer 40,000: Darktide Network & Connectivity Feedback
1

Issue Description:
Each time I try to access a game (after creating the character in prolog), the game will show an error 4008 and refuse to let me join the servers.
I’ve tried everything I find here and on other websites (changing my DNS, disable IPv6, purging DNS, no VPN, verify all the files).
I’ve come to the conclusion it is because I use Free as a ISP in France (Paris). Same issues for a lot of people on the 11/22/2022, 12/22/2022 and 03/24/2023 (KNOWN ISSUE: Crashing Since Latest Update - #9 by GreenLegRyu).
Might also be from the last updates from the recent posts on the Network category.

First time playing the game yesterday, version 1.0.52.

Unplayable outside of prologue.

Crash Report (If Applicable):
