Loading this assembly would produce a different grant set from other instances (Exception from HRESULT: 0x80131401

Hi, I’m new to the UiPath Studio and working through the developer academy courses and I keep getting the above error message when I attempt to copy and paste on activity within the same process. Although it’s helpful right now to familiarise myself with the software, I can see this becoming inefficient in the future. Any ideas why this error is occurring and how to fix it on my side?

Thanks for the help!
