Thanks to Martin, who pointed out it may be autotune I found out It was autotune and possibly echoboy. I Have been running empty Cubase 10 project Vst plugin manager to see what plugin name it halts then crashes on. So far it’s been Autotune and echoboy. So After taking the plugins dll out, I opened a project file using both of these plugs (which were now removed) and the project opened and played back when it used to just crash without ever getting to load the project. Moving forward I Guess this is the best way to see how Crashing updates are affected by a plugin. Let me know if this helps.
