Hi @rshek,
Are you still having this issue? Do you have access to the original project directory?
Can you update to the latest patch and try re-importing the project?
The workaround I used was to use older .json file. but its missing all the recent jobs. Just started random new jobs (which obviously failed) till it ran up to most recent job no. Havent encountered the issue recently. Thank you for following up Stephan!
