1. Reinstalling looksmenu
2. Moving the F4SE folder from Looksmenu in MO2's mods folder to Fallout 4's Data folder and overwriting existing F4EE.ini and F4EE.dll (from previous version, don't know how they got there).
I also had to move all mods with F4SE folder (Like Place Anywhere, Better Console, ESP Explorer etc) from MO2's mods folder to the Data folder manually in order for them to work now.
This worked for me, but I don't know if it'd work for you especially if you don't use MO2.
If you don't use MO2, try moving your existing F4EE.ini and F4EE.dll somewhere else/delete them and reinstall Looksmenu.
