Hello,
I know this is a known issue from... 2020.
But exactly the same as described in the last topic happened to me.
Context: I bought ACV with season pass and DL it without problems, then no time to play -> delete (December 2021).
Last week (04.2022) : Re-installed ACV from a local backup on my PC/first boot disc. -> Auto DL Ragnaroek DLC
1rst issue: Game crash on start screen, as soon as you press any button
Solution found on internet / other forums as the ubi forums = Delete all the DLC folders + Verify files -> +53GO new update to download... then I could access for the first time to the menus (new game, Options, Discovery tour, etc.)
2nd issue: Game crash after choosing the 3 level of difficulties.
I used again "Verify Files" -> +8GO new update to download....
Then again = the game crash after the choose the 3 level of difficulty
Since the first installation, I've been waiting for ONE full week to try to play to this game and the Ubi servers are so slow..
It seems there are issues, especially since the implementation of the new Ragnaroek DLC.
Please let me out of this no fun Parkour.
