W0LU caused by a script you have installed
Remove everything in %localappdata%\Plutonium\storage\t6\scripts and try again.
If it works then you can either stay like this or try to put the mods back one by one and see which one is causing the error. If you find it and you really want to keep the script then make sure you followed all the instructions from where you downloaded it.
Also could be an outdated script
