Cubase 12 pro issues after using Melodyne

I just downloaded the latest update of 12. I also upgraded to Melodyne from essential to assistant I now have issues where I can still hear the audio but there is no visible wave forms in the session edit window. and up top the sample ruler is there instead of the bars and beats. I don’t know what happens. But the CPR files are now four times the size of what they were. I had no issues until I started using Melodyne.
