Database: ERROR (spawn error) after re-installation

open

#1

Hi,
I had to reinstall cryosparc after a complete rebuild of our machine.
Before, I copied the whole database to a separate disk and copied back the folder now.
Installation of cryosparc goes smoothly, however upon startup the spawn error appears.
This is only true for the old database, if I create a new it works.
Already deleted all lock files in the database path without success.
How should I proceed?

Best,
tarek
