Every mod is composed of patch_(number) files that you normally have to manually rename and place into the helldivers 2 data folder
The mod manager does this for you, but it isn't perfect and will sometimes miss or fail to remove these files and when the game gets updated you'll CTD over and over until you remove them.
Go into your local files by right clicking HD2 in your library, go to properties and picrel, open up the data folder and search for "patch_1" "patch_2" "patch_3" in the explorer search and remove every file that shows up.
If that doesn't work delete your entire %appdata% helldivers folder. This will reset your keybinds and settings.
