I ran into this last week as well. I ended up just batch-converting all CBRs to CBZs using ComicRack. I did this by creating a smart list to show only CBRs based on the extension. I then selected all, right clicked, and exported as CBZ. ComicRack converted all files and automatically embedded the metadata.

There may be a better way, but this was pretty simple for me

You made my day! Thanks for the great support.

Thank you Tom! Any idea on that ETA?

I am having the same issue on Windows 10 and Chunky. Downloading in Chunky via odbc works fine on 1.10, but presents this error on 2.0. Stream works fine
