Which version of Movie Studio are you referring to? If it is Movie Studio 18 or 2022, they are not VEGAS products and support for them is not available on this VEGAS Community forum. However, support for it is available at https://www.magix.info/us/video-forum/movie-edit-pro/

Please see also this thread.

If you actually mean a VEGAS Pro update, you should post your issue on the VEGAS Pro forum.
