Debug cell not working on macOS

[aljabadi]

Issue Type: Bug

Debug cell launches the debugger but won't stop at breakpoint or show any signs of any execution. Trying to access the variables before the first breakpoint in debug console throws an error which probably means it is not just a UI issue. The debugger works just fine in interactive python files, but not in notebooks. This issue reproduces in the Insiders version. A gif will be attached.

As an addition, I found that if you add the breakpoint in the first line it works, while a breakpoint in any other line is ignored.

After some testings, it seems that the issue is linked to ipykernel version 6.4.1
I have downgraded to ipykernel 6.4.0 and it works perfectly
