I installed Cubase 15 Pro for the first time yesterday. It has become unstable twice, in two launches, both times with Sine player (current version).
I have attached the two most recent crash dumps and would be grateful for any assistance with this issue.
Thank you, Stephen
The first one seems to be a problem with the Nektar Impakt LX61 SOftware:

The stack trace seems vaguely familiar to me, I think I have seen that one before here.
Anyhoo, best to check whether you have the latest version of that Software installed, else maybe check with their support.
The second one is definitely an issue with the Sine Player:

That is a very short stack trace, never seen that before. But a Null pointer read pretty much points to the SINE player VST as the culprit imho.
Thank you very much for the helpful and quick reply. I do have the latest Sine player installed. It’s all beyond me, so I’ll report it to Orchestral Tools (I’ll mention that I’m a recently rostered demo composer for them 
) and Nektar support.
