Guys, look no further, there is a major issue since 12.0.10 which causes Cubase to crash when inserting certain plugins and even opening plugins that are already loaded (this includes Waves but isn’t limited to).
The crash probability is so high that it is indeed impossible to work in this current state.
There are several reports on this topic, which is also more appropriate to discuss about this issue since the moderators are reading it more frequently : Cubase 12.0.10 - performance issues
