Error code -9405

[tooold]

I've been getting this error toward the end of a 4.5 minute session I'm working on. It's an odd one, all tracks are tick-based for working on getting the right tempo for a particular song. It's also at 96k, and reasonably big with some VI's, all probably a bit much for my M1 Mini.

But I can't find anything about this error code... has anyone seen it before?

The other odd behavior (that might or might not be related) is that PT is occasionally losing the drive definitions that show up in Workspace - all drives, regardless of previous settings, will revert back to Transfer. I haven't been able to see a pattern.

Thanks,

Myles
