Suggested fix (unconfirmed): Update your graphics card drivers and verify the game files through Steam.
Suggested fix (unconfirmed): Turn HDR on in your settings. Alternatively, adjust your graphics settings such as DLSS.
Suggested fix (unconfirmed): If you use an AZERTY keyboard switched to QWERTY in Windows, remember that the prompted 'A' key corresponds to the 'Q' key on your physical keyboard. Press the correct keys within the small time window as they appear.

Suggested fix (unconfirmed): Press the 'A' key at the exact moment the prompt appears on the screen rather than spamming it. Alternatively, try to bypass the climbing section entirely by jumping around the rocks.
Suggested fix (unconfirmed): Use the top-screen labels to guide your search for the notes. For the 5th note, look on the ledge above the entrance doorway in the large chamber with the second Nymph under "The Liberation of the Nymph."
