"The application does not have the cloud notification capability" on xbox live sign in on unity

Whenever I try to sign into Xbox Live on my Unity game (using creators program Unity plugin), both on UWP PC and Xbox One, the game throws an exception:

Exception thrown at 0x00007FFAEF0AA899 in Boulder Falls.exe: Microsoft C++ exception: Platform::COMException ^ at memory location 0x000000E51B6FEC20. HRESULT:0x803E0110 The application does not have the cloud notification capability.
WinRT information: The application does not have the cloud notification capability.
Stack trace:
 >[External Code]
The program '[5896] Boulder Falls.exe' has exited with code 0 (0x0).]

I am using the included prefab to sign in, and I do have developer mode enabled on both the PC and the Xbox, they are all in the correct sandbox, XboxServices.config has XboxLiveCreatorsTitle set to true, and the account I am using is in the test account list. Is there any solution to this?

Edit: If I try to continue past the exception, it throws another one:

Exception thrown at 0x00007FFA7F1BA839 in Boulder Falls.exe: Microsoft C++ exception: Platform::AccessDeniedException ^ at memory location 0x000000D2BA3FE740. HRESULT:0x80070005 Access is denied.
WinRT information: A network capability is required to access this network resource occurred

I fixed it, I just rebuilt the program in a new folder from Unity, and compiled it from Visual Studio 2017 instead of 2019.
