Cubase Pro 15 crashes during loading

I’ve just rebooted my PC and tried to load my project in Cubase and it crashed. I’m attaching the crash dump.

The crash is caused by the BBCSO plugin.

Do you have the latest updates of the plugin installed?

I have version 3.4.17, and there don’t appear to be any updates for it. Weirdly, I have a very similar project with BBCSO and it loads fine. Also, weirdly, when I restarted Cubase and tried loading the same project it went fine (and the BBCSO track plays fine). For the time being I think I’ll swap it for a Vienna patch just to be safe. Thank you for investigating it.

By the way, the OSNAME above says Windows 10, but I’m running Windows 11.

That is the internal name, even Windows 11 is internally named Windows 10. The tag OS_VERSION has the build number and that tells it is Windows 11 24H2 (the number 26100 is the relevant part). Windows 11 started with build 22000.

Thank you for explaining that.
