Hello Jason Teunissen,
The “Stopping debugging session…” popup usually means Studio Pro is trying to shut down the local runtime (Java, Node, database).
Most of the time it’s quick, but if the laptop hasn’t been restarted for a while, those processes can hang and it takes much longer.
In my case, a simple restart of the machine prevents it, and if it does get stuck, killing the leftover java.exe or node.exe processes in Task Manager closes it immediately. So it seems more related to the environment/resources than the project itself.
Regards

If you're a masochist like me try using the mac version... Where the debug outline on activities lives forvever when when debug is disconnected, and restarting my computer is a daily ritualy because the modeler can't handle a day of dev without always crashing.
