Failing to decrypt

[ngagne]

Hi, I've followed the guide a few times and verified all of the programs are running as expected. I installed the Apple Music beta, logged into my paid account, set audio quality to lossless, played a track, etc. Everything seems to be working when I start the script, but it fails on the decryption part. What can I do to debug decryption failure?

[WorldObservationLog]

raised DecryptException?

[ngagne]

yes, seems to fail when decrypting the sample

[WorldObservationLog]

It's a common problem. Try to restart the script and download it

Thanks for your response. Here is the error I'm seeing:

I've tried this on Windows x64 and MacOS arm64, but I'm continuing to face the same error above.
