and just in case, I will just leave the commands to downgrade from
1.6.1170/1.6.1130 straight to
1.6.640 down below:
download_depot 489830 489831 3660787314279169352
download_depot 489830 489832 2756691988703496654
download_depot 489830 489833 5291801952219815735
From
1.6.640, if you want to go back further to
1.5.97 you can use Halgari's patcher to achieve that (either the
BestOfBoth_1.6.640.0-1.5.97.0 or
FullPatcher_1.6.640.0-1.5.97.0)
Press windows + R then steam://nav/console in order to get to steam console.
Do it one by one, let the 1st one finish downloading fist, then enter the 2nd one, once it finish, enter the 3rd one.
You can find all the 3 packages that are downloaded in ”Steam\steamapps\content\app_489830”
Then just replace your “steamapps\common\Skyrim Special Edition” files with the ones in “depot 489831” “depot 489832” and “depot 489833” in that
order.
To check what version you currently have installed, right click on SkyrimSE.exe > Click Properties > Click on Details > Look at "File Version"
IMPORTANT: If you experience any kind of crashes CTD after downgrading, chances are you do not have
BACKPORT EXTENDED ESL SUPPORT in your load order. This mod is now REQUIRED if you are playing on a downgraded 1.5.97 or 1.6.640 game (thanks bethesda). Grab it, install with your mod manager and you should be good to go (and make sure you have all the required dependencies which is SKSE and Address Library for your version of the game)
