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
