Hello ,
Thank you for contacting us regarding this saving time issue you are facing. I was wondering if this is happening with all files or just specific ones?
If this behavior is happening to all files it could be due to the amount of saved libraries on your machine that Twinmotion needs to reference/read. Could you let me know how big your local libraries are: User library, Quixel Cloud Library and Twinmotion Cloud library. They are located by default in your documents folder: C:\Users\%USERNAME%\Documents\Twinmotion2022.1
If you have a lot of downloaded assets from the Quixel or Cloud library (Skydomes) you can delete the contents and Twinmotion will load/save faster. However you will have to redownload assets as needed. We are currently investigating this behavior to help resolve this behavior in a hotfix/update.
Hope this helps and if you are still having problems you can contact us directly with this link or from the home page by pressing the [ contact us ] button. https://twinmotionhelp.epicgames.com/s/case-community-page

Vincent B.
