To enable starfield's achievement after using the console, you can install the achievement enabler mod from nexus mod: https://www.nexusmods.com/starfield/mods/252?tab=description

i'll paste below every step that you need to follow;

Steam Version Instructions:
1.) On the ASI Loader GitHub page (https://github.com/ThirteenAG/Ultimate-ASI-Loader) scroll down to the "Description" section and download "bink2w64.dll"

2.) Go to your root directory of your Starfield game (steamapp\common\Starfield) and rename the "bink2w64.dll" that is already in there to "bink2w64Hooked.dll"

3.) Now copy over the "bink2w64.dll" downloaded from GitHub (from step 1 above) and place this in the root
folder of your Starfield game (steamapp\common\Starfield)

4.) Create a new folder in the root directory of your Starfield game called "Plugins" your folder structure should look like this (steamapp\common\Starfield\Plugins)

5.) Download the mod from this page and place the "starfield-achievementenabler.asi" file from this mod inside the the "Plugins" folder

6.) That's it enjoy! By the end of following these steps the below is what
you folder/file structure for this mod should look like:
Starfield\bink2w64.dll (downloaded from GitHub)
Starfield\bink2w64Hooked.dll (your original bink2w64.dll that is already in the folder which you have renamed to bink2w64Hooked.dll)
Starfield\Plugins/starfield-achievementenabler.asi (downloaded from this mod)

UWP Version Instructions:
*Some have advised within their root folder for the Windows version of the game they have the bink2w64.dll and the dinput8.dll, or one or the other. If you have the dinput8.dll in your root folder follow the below. If you have the bink2w64.dll follow the above. If you have both you can follow either but don't do the this for both!

i tried this myself, works perfectly!
