Thank you very much for the information! It's a tremendous help for us to reproduce the problem on our end.
It's great to hear that you are unblocked by the problem for now. Other users who read this post can do the same to avoid the crash.
It appears that updating Reader to the latest version 11.2.0 (instead of installing a fresh new copy of Reader 11.2.0) has introduced a new problem. We will investigate further and try to fix it soon.
Thank you again for your help!
