If you encounter a problem where you cannot commit changes in Git – neither through the terminal nor via the GitHub Desktop application – the issue might be a freeze during the Git commit process. This is often caused by GPG lock issues. Below is a concise and step-by-step guide to resolve this problem.
Open your terminal and try to perform a GPG operation (like signing a test message). If you see repeated messages like gpg: waiting for lock (held by [process_id]) ..., it indicates a lock issue.
