Update on my exe-not-running problem. It wasn’t the preview at fault - it was the sqlite plugin. The author just updated it yesterday (thank god! - for me) and now the build runs fine. Interesting that there was no message or any sign that anything was happening when I tried to run my app before - you’d think there would be some kind of error message or log?
TLDR: Not a problem building with 4.11
Thanks!
