I have been seeing this error for quite a while now. Today, I tried to resolve it by myself. After a bit of Google searching, I found multiple troubleshooting methods, but none of them worked. Here are the methods I have tried so far:
- Went to recovery mode and checked the security settings
- Created a second user account, added Apple Pay there, and then tried adding it back to my original user account
P.S. I have not reduced the security of my macOS at all.
I would really appreciate any help fixing this. Thank you very much.

I don't know if I should be happy! The pain is real!
