So I installed F4SE.
The game broke.
I tried a few things to fix it. The game wouldn't even start on Steam. So now I'm looking at the Disk Space Allocation bar. I start with a new installation without active modifications. I hope that helps. Did anyone else have a problem with it or did the bat work for you?
Finally googled and get solution- https://appuals.com/fix-fallout-4-script-extender-f4se-not-working/
