@subratkatiyar Thanks for filing the issue
When/how are you able to get this?

I assume it is happening on your terminal when you do certain action?

[subratkatiyar]

The extension was working perfectly fine. I have auto-updates enabled.
Randomly one day, as I was trying to debug some python code. I get the error "type": "debugpy", is not recognised.

That's when I saw this error in extension panel. [Screenshot attached.]

I have tried re-installing the extension but the issue persists.

[SimonHaneke]

I have the same problem.
I had the python extension deactivated for a while and tried to activate it today. This failed already because the extension tried to activate the Python Debugger first. But the Python Debugger expected the Python extension to already be active which lead to a loop of notifications that its not possible to activate the extension.
Then i reinstalled the extension and got the error described in this issue.

[ReedGraff]

+1. Have the same problem.

Solution: Roll back to old version until this is fixed... I rolled back to 2025.0.1

[anthonykim1]

Not sure why this is happening. Was there some code change related to debugger waiting for Python extension? /cc @eleanorjboyd @karthiknadig

[karthiknadig]

This is installation and extension packing bug. We don't do anything here specifically.
