[2022] [PC] Game won't start anymore

Hey there.
Writting this because I'm having quite an annoying issue : my game isn't able to get even to the main menu.
Been playing AC Valhalla since it's release and never had such annoying issue, until now.

I've been playing w/ mods (Forger - Eivor Customization), and I even got to remove them, thinking it was what was preventing me from playing the game.

Here's my specs :

• i7-9700K @ 3.60GHz
• Nvidia RTX 2070
• RAM : 16Gb
• Drivers up to date

I've been scouting on the web for an hour, looking for some solutions. Yet, except updating my GC drivers and checking missing files for the game itself, none of those managed to fix it. Even setting the game as high-priority in power management menus.

Any of you guys got an idea how to fix it ?

Thank you!
