Essaye de voir si ton F4SE se lance bien.
Message de RedSinister sur NexusMods :
"VORTEX user, make sure you can launch the f4se_loader.exe from the game installation folder beforehand! If the game is not open, Mod Config won't appear on the menu list. Yes, other mods can still work well simply by running directly from Vortex. But, MCM mod does not count
Your best bet is to manually install F4SE and MCM to make it work (only copy-paste file, not difficult to do)
A conflicted/corrupted plugin will also prevent the Mod Config from appearing, so go to your game's installation folder.
Then go to Data > F4SE > Plugins and delete everything inside. Next, launch the game through the f4se_loader.exe in-game installation folder OR Vortex f4se, the MCM mod will be detected
If launching from Vortex Fallout 4 Script Extender (f4se), make sure to set it as Primary"
