When using Unity Hub the standard debugger can't hookup to the Unity Editor because multiple instances running. The Hub is also seen as a Unity Editor. (If I close the Hub everything is working fine.) This will probably be fixed with some changes in the launch.json file.
Hi @maxartz15 We identified the issue and the VS code debugger should have an update coming to fix the issue. Meanwhile, there is another post with the problem where other user mentioned a workaround. https://forum.unity.com/threads/unity-hub-and-vscode-debug.514908/ Thanks for reporting, hope this help
