I am not having the same problem of the product locking up. It seems to have been caused by either one of these two things, or both in combination:
1) When the NewBlue Titler or Effects prompted me to sign on when I started Movie Studio Platinum 16.0 build 109, I ignored it. (Note. This product is annoying. I paid for this, so why does it prompt me to login with my name and password once again?)
2) In Options --> Preferences --> VST Effects
I had enabled both a current and prior version of Acon Denoise at the same time.
