[SOLVED] The problem was a disabled track. Removing the disabled track restored the ability to freeze and brought my project file back to life.
More results of the test coming up…
Results are in: It’s the simple act of Enabling the disabled track that solved the issue. There was no need to remove the track.
So, there was nothing wrong with the track or its plugins.
Disabling a different track with different types of plugins caused the issue again. So it does not seem plugin specific.
It’s a bug (highly probable) in Cubase related to Tracks in a disabled state.
Solution (for me): Don’t use the Disable Tracks feature.
Which is fine, since Render In-place, its killer co-feature, is useless to me for now several reasons, this being just one more (no pre-fader render option being the main reason).
I added this to the issues forum:
