When I open Script Dashboard, I get a blank screen with no options to add a script. No other errors encountered on other screens, Dashboard works fine.

Thank you for reaching out to the Devolutions forum. The script dashboard will remain empty until you create a new PowerShell entry.
The attached picture illustrates this process.
