What is the rule in the Kotlin code style that insists on adding a blank line before else branch in when? It must be new or a bug. My Blank Lines / Minimum blank lines are all set to 0 except Before declaration with comment.

It only insists on a blank line if the previous case had multiple lines. It's not just the else case. Put a case 4 -> before the else and you'll see the suggestion for a blank line before 4 ->.
See the guideline in https://kotlinlang.org/docs/coding-conventions.html#control-flow-statements: "In a when statement, if a branch is more than a single line, consider separating it from adjacent case blocks with a blank line"

got it! thanks.. that explains my case.. but it didn’t do it previously and there seems to be no way to turn it off

for multiline I prefer to use 3 -> { … }
