visual studio code – cannot open vscode on macOS after update

Vs code was running perfectly fine on my MacBook Pro mid 2012 with macOS Catalina 10.15.7 (19H2026). But then I clicked on “restart to update Jupyter extension” the app closed and did not restart. Now when I click the app icon nothing happens. The little dot below the app pops up for one second indicating the app is open and then immediately disappears.

I restarted my Mac, downloaded vscode again and “reinstalled” it (just overwritten the old app), still the same issue.. Even deleting my settings.json does not do anything..
Is there another way to “reset” it?
