The root problem is lost of communication to COM, resulting a COMError. The exception raised do not seem to have a fixed format or has been changed since the pyscope code handling it was written.

I can confirm that for the past 3-4 months this error has been showing up during tilt-series collection on Krios1 and has increased with time. I don't think I've seen it on Krios2, and I'm pretty sure I haven't seen it on non-Krios scopes. When Krios1 gets a PM this should be brought up.
