Hello @nyusuf

Check the below thread for your reference

Invoke Workflow Activity does not load arguments

@RSalamow the issue might be with studio as I tried with same system activities and it is loading first try to close project and delete the .nuget folder in c:\users\username\.nuget and then recreate and check if not try to do a reinstallation cheers

When i click on import argument but it doesn't work

Drag and drop the flow you want to invoke Other things you can try is click on save all and refresh than try Or restart studio and than try to drag and stop the flow Hopefully it should be resolved

Hope it helps!!
