Some, but not all, Yubikeys cannot be read by e.g. gpg --card-status (nor any operation using it) as of 2.2.36:
gpg: OpenPGP card not available: Card error
- Yubikey 5C NFC is affected;
- Yubikey 4 Nano is not;
- v2.2.35 works with both.
In the linked Reddit thread, one user confirms my (broken) experience with the 5C and another (working) with the 4.
