I've also a probleme with Al language debugger since Al Language version 11 has been installed. When I set a breakpoint in a Microsoft standard object (opened in .dal with Al Explorer) or in an event subscriber in one my codeunits, the debugger doesn't stop on these breakpoint.
When I debugg step by step, a new page opens on VSCode and says "No content available" when it should instead enters in a Microsoft standard object.
I work on an OnPremise environment. I try to debug the codeunit 91 Purch-Post (Yes/No) and to subscribe to the event OnBeforeConfirmPost, but I can't enter in the event, neither can I rise my event publisher.
