Research direction
Start with the import path from InProcessKernelManager() into ipykernel/debugger.py and reproduce the failure using a fresh ipykernel 6.3.0-or-newer environment. Check the PyCharm or VS Code debugger attach behavior; done means the debugger can attach without replacing ipykernel.debugger with a fake module.

Description
The problem starts at version ipykernel==6.3.0 and up. I created a fresh venv in PyCharm and this is what I see in the "Python Window" when clicking the "Attach Debugger" button:
When I use the PyCharm "Debug Server" it locks up forever when trying to connect.
Other team members using vscode are having the same problem.
I'm currently working around the problem with this code at launch of product:
class FakeDebuggerModule:
Debugger = None
_is_debugpy_available = False
import sys
sys.modules['ipykernel.debugger'] = FakeDebuggerModule
The code my application is running which causes debugger.py to get imported is:
from ipykernel.inprocess import InProcessKernelManager
InProcessKernelManager()
