WARNING - Unable to 'Single step' since Visual Studio Code 1.78.0

Hi, when I launched Visual Studio Code yesterday, it told me it had updated to 1.78.0 and asked me if I wanted to keep the new theme or revert to the old one. I chose 'Revert'. Since then, I'm unable to single step (F10 through code). The 'next line' is never executed but F6 brings me back there. A few times of this and the app stops altogether. If I put a break point on the next line and hit F5 instead, it goes there. Not very convenient. Rebooting the computer didn't help.

I didn't make the connection between both until this morning when, from a different computer (was going to troubleshoot that problem on the other computer later on), I stopped and relaunched Visual Studio Code. I had the same update and chose the same 'Revert' (didn't make the connection at that time). Again, while Single Step was working minutes ago, since this update, it's not working there. So something in that update broke the single stepping of Monkey C code :-(

Now I have no choice to troubleshoot, unless someone already have the solution lol.
