Hi @armbrustered,
I think it might be easier for you at this point to reinstall the cryosparc2_master package; it looks like something must’ve become corrupted, and reinstalling is the safest way to fix this (you won’t lose any data).
Before starting, I suggest making a backup of your database: https://guide.cryosparc.com/setup-configuration-and-management/management-and-monitoring/cryosparcm#cryosparcm-backup
You can then make sure cryoSPARC is fully turned off (i.e. kill any processes related to cryoSPARC)
Then, delete the cryosparc2_master folder (e.g. rm -rf cryosparc2_master)
You can then install the cryosparc2_master package normally (follow the steps to install cryosparc2_master as a “Master Node”):
Just make sure you specify your original database folder location when installing so that all your old data will be preserved.
