Prompt
Help me fix Chrome sync conflicts with the goals and materials below. [input] Goals and usage situations: I'd like to get stuck on Chrome sync crashes and decide what to do next. Resources to review: Bookmark differences and account status by device 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 device, account, synchronization scope, and time of change and preserve the original data. [Results to be created this time] Change only the parts where the cause has been identified into preventive rules. Present items to be checked regularly and abnormal signals/check cycles according to the usage environment. Please do not recommend installing general optimization programs or disabling unnecessary security features. [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] Ensure that causes and preventative actions are linked and maintenance burdens are realistic. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
