Edit: just restart the project. I was able to get past this error by creating a new project
Clicking “labeling queue” button on the “Data acquisition” page brings me to an empty page with the text “An error occurred when serving your request: No metadata yet, block is not trained”.

I am glad you were able to resolve your issue. Do you currently still experience this issue on the old project? And if so, can you please provide the project ID for it? Just so we can report this to our engineering team.
