Prompt
Help with file open error tasks according to the goals and materials below. [input] Goals and usage situations: I'd like to get stuck on a file open error and decide on my next course of action. Resources to review: File Format and Error Message Conditions and Constraints: Please proceed based on the provided data, and mark any missing facts as requiring confirmation. Previous attempts and records: This is my first attempt. Please proceed from the parts that can be confirmed in the current data. [Key points to check in this topic] Check the extension, actual format, app version, and possibility of damage. [Results to be created this time] Create a symptom description to send to customer support or repair personnel. Organize device, version, occurrence time, reproduction steps, attempted actions, and error phrases, and hide account information or secret values. Separate causal speculation from actual observations. [Working Principle] After checking the operating system and version, provide guidance on the relevant environment. Before changing files, accounts, or settings, explain the implications and recovery methods, and don't tell anyone you've actually deleted a deletion candidate. Do not arbitrarily disable business management policies or security protections. If there is no input that will change the results, ask only the necessary questions first and proceed with the parts that can be confirmed with data. [Completion criteria] Make sure the recipient can understand the same symptoms and that there is no unnecessary personal information. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
