I'm sorry for the frustration. I was not able to reproduce locally, which just means we need to dig in a bit to understand why this is happening on your machine.

Have you applied all updates to ProSeries 2019?

Are you on Network, Standalone Professional, or Basic?

Have you tried selecting multiple clients, and clicking "Yes All"?

When it crashes, do you get a dialog asking you to report the problem? If so, can you put a message "for orlando" in there so I can go in and dig into the details?
