Thank you for your post!
Based off you error message - User account '{EmailHidden}' from identity provider 'live.com' does not exist in tenant 'Microsoft Services' and cannot access the application 'c44b4083-3bb0-49c1-b47d-974e53cbdf3c'(Azure Portal) in that tenant.
.
Can you make sure that the user you're trying to login with does exist within the "Microsoft Services" tenant?
- If the user doesn't exist, you can follow our Add guest users to your directory in the Azure portal documentation to add your user.
Additionally, if your browser is automatically redirecting you after clicking on "view existing subscriptions...", and logging-in with a different user, can you try selecting the link within a Private Browser to see if that resolves your issue?

I hope this helps!
If you're still having issues, please let me know.
Thank you for your time and patience throughout this issue.
