Upgraded to 18.0.1, so cannot provide any further troubleshooting with this issue. Issue is no longer occurring in v18.

Sorry for reviving this old report, but it's one of the top search results for this error, so I hope it might be useful for someone stumbling upon the same issue

I've had the same issue occurring on NC 29, and according to forum posts it seems to happen now and then with other versions as well.

What I've found is that running occ files:scan-app-data seems to solve this problem.
