Cannot trigger workflow within workspace

**Describe the bug**
If i open my project with "Open Folder" all just work fine, but if i open it as workspace (what is neccessary for other Extension-Configurations that are global for all developer) there happens nothing... If i click on "Trigger Workflow" really nothing happens. No errormessage and all the Output-Log shows is:

Activating GitHub Actions extension...
...initialized

Tried it with multiple projects and all have the same behavior.

**To Reproduce**
Steps to reproduce the behavior:
1. Open the Project as Workspace
2. Click on "Trigger Workflow"

**Expected behavior**
The workflow should run...

**Extension Version**
v0.26.2

Reproduce the issue using the listed steps with extension v0.26.2: open a project as a workspace and select "Trigger Workflow". Compare this with opening the project via "Open Folder", and inspect the GitHub Actions output showing only activation and initialization. Done means the workflow is triggered from the workspace and the output reflects the run.
