I have an up-to-date, paid developer account, but feedback assistant on Monterey and iOS 15 won't log in. When I try logging into the Feedback Assistant website, it says I'm not currently enrolled in either a public or developer beta. How do I fix this?

I'm converting an existing project to Metal. It currently can run computations on other GPU platforms like CUDA/Optix, OpenCL or the CPU using common headers for expressing the platform-independent calculation logic. I've imported these headers into Metal and gone through the long process of annotating all of the pointer references to make the Metal compiler happy and it's successfully compiling and creating a metallib from my trampoline kernel. The issue is when I run the program and it gets to the point in the Metal setup process where it needs to create a compute pipeline state from the functions I've retreived from the library. The application hangs forever (with the synchronous call) and the state is never created, nor is an error ever thrown. I've discovered that when this is happening, the MTLCompilerService process is running at 100% CPU usage and sampling the process seems to show that llvm is endlessly optimizing the code, but I'm not sure. Is there anything I can do to fix this issue? I can provide a sample project with the compiled metallib if that helps narrow it down.Sampling process 1005 for 3 seconds with 1 millisecond of run time between samples Sampling completed, processing symbols...
