Product and Version :Vscode 1.34
OS Version :Windows
Live Share Extension Version: v1.0.123
Target Platform or Language:Python
Steps to Reproduce / Scenario:

@Luchiwis Apologies for the confusion! If you open the Settings window, and then search for livesharedebug, you'll find the Enable Guest Debug Control setting. If you check that, then guests can start the debugger on their own. We turn this off by default as a security mechanism.

Hoping the answer by @lostintangent answered your question and unblocked your. Closing issue.
Why don' t you make allow the default? We are developers who know what we are doing using vscode.
