As they are “converging” more and more APIs into the Desktop OS, they may got “integrated” the new “bug” from a common core codebase. Your issue seems fixed on the Xojo end, maybe a similar fix must be done in the macOS part of the Xojo framework. If Ventura starts crashing System.Version, it will demand an urgent R4.1 patch version because it’s a critical part.
I think the confusion is due to this extra security update - see Ventura 13.2 (a) (22D7750270d) crashes Xojo - #14 by Rick_A
Once I applied it to 13.2 beta, which bring the Ventura Version number to 13.2 (a) I am now seeing the same OutOfBoundsException
This happens for me with English language, so I think it has nothing to do with the system langauge.
I know. This issue was extensively discussed, and that was already pointed out in issue case https://tracker.xojo.com/xojoinc/xojo/-/issues/71254
