This occurs when the process of proving key deserialization fails, which can be due to several reasons:

• Passing it in an unexpected format (difficult to determine without reviewing your code),
• Executing the setup with a different engine, such as bellman, while attempting to generate proof with ark using bellman artifacts,
• Version mismatch, where the setup is run on an older version of Zokrates.
