Thank you for your feedback. I am struggling to figure out what jobs are not plotted in the tree in my case.
The warning is precluding me from starting new jobs, as the parameter/input pane on the right side is not accessible once the warning comes up.
I’ve tried e.g. importing particles from a “stuck” project into a new one through setting up a 2D classification job, and I get the following (generic python?) message: ‘NoneType’ object has no attribute ‘getitem’.
Any ideas on what the underlying issue might be?
Alternatively, assuming it is not a corrupt database issue, can I re-install Cryosparc2 and re-import the data/jobs to restore the projects to their current states?
