I need help restoring lost iCloud file

My name is Yalemsew, and I am seeking your assistance in recovering some missing files from my iCloud account. On December 19, 2024, I temporarily adjusted the date and time on my Mac to approximately one year earlier. After reverting the settings three hours later, I discovered that some files from iCloud were missing.

I am unable to determine the cause of this issue or identify any specific pattern related to the missing files. Your guidance and support in resolving this matter would be greatly appreciated.

Thank you for your attention to this issue.
