Hello ,
Thank you for posting in the community and it seems like you need to find the content of your scene. Did you model the elements far from the 0,0,0 origin in Sketchup?
Try selecting the elements in the scene graph then press [ F ] key for Zoom to selection. Or it could also be that you are in orthogonal view and need to press [ O ] key until you are back in perspective. Refer to the Help Menu > Shortcuts
If there is a UI issue deleting the Config folder will reset all the default settings to Twinmotion.
C:\Users\%USERNANME%\Documents\Twinmotion2022.2\Config
Hope this helps.
Kind regards,
Vincent B.
