Any suggestions?
May I ask is it a MAC or Win version we are talking about?
Do you have the latest (4.1.1) version of SketchUcation tools installed? To be sure please download and install the latest version from here: https://sketchucation.com/pluginstore?pln=SketchUcationTools Restart SketchUp and retry.
Does the problem still existing?
Update: Also could you please check if the file C/Users/spilz/AppData/Roaming/SketchUp/SketchUp2021/Sketchup/Plugins/SketchUcation/SCFLicence/Win64_27/SUEX_SCFLibrary.so exists on your hard-drive?
