I upgraded to Catalina last week end ans Wavelab 9.5 Elements with my waves plug-ins was working like a charm.
I bought upgrade to Wavelab Elements 10 and installed it smoothly
I imported the settings of previous Wavelab.
Wavelab Elements 10 is launching normally but as soon as I try to enter into Preferences or trying to make a render with plugin in master section, it does crash.
I don’t know if it is à Catalina matter only or if my settings were not accurate for this new version.
In the meanwhile, I’ll continue to use 9.5 version which appears to be quite reliable on Catalina
