Lunchbox Launch application problem

Hi,
since I started working with Rhino8 the LunchBox launch application component doesn’t work
and I get this message :
"System.ComponentModel.Win32Exception (5): An error occurred trying to start process ‘Z:\ToBack 19_04_24\RhinoModeles\Jewellery(Home)\Work 19_04_24’ with working directory ‘C:\Program Files\Rhino 8\System’. Access is denied.
at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo)
at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)

at LunchBox.LaunchApp.SolveInstance(IGH_DataAccess DA) in C:\Users\nate\OneDrive\Documents\bitbucket\lunchbox\application\Nodes\Workflow\LaunchApp.cs:line 72"

Can someone help?
Thank You
Solomon
