Lines 105 to 115 in 897f7a8

	protected async doInit(): Promise<void> {
	this.debugConfigurationTypeKey = this.contextKeyService.createKey<string>('debugConfigurationType', undefined);
	this.initialized = this.preferences.ready.then(() => {
	this.preferences.onPreferenceChanged(e => {
	if (e.preferenceName === 'launch') {
	this.updateModels();
	}
	});
	return this.updateModels();
	});
	}

My idea would be adding a callback workspaceService.onWorkspaceChanged(this.updateModels) on line 108, any thoughts?
