Quantrix 6.1.0 cannot add actions

When I clicked ‘add action’ from the script manager UI, I got this error. I also opened previously built Quantrix files, which had lots of grooovy scripts. None of those scripts are enabled, but in the past all scripts have worked fine. Please advise how to fix it. Thanks!
