Error Occurred. Did the Dll Inject properly?

I get this error when I use WeAreDevs_API.dll for my C# windows form application, I am executing it, and it says injected with a PID, but whenever I try to run a script it gives me the error mentioned in the title. 

I am running Windows 11, .NET 6.0, and the latest version of Visual Studio and Roblox.

Any help is appreciated.
