Hello Sungeun,
Thank you for reaching out to Microsoft Q&A Support forum.
Your OneDrive files keep getting deleted and no longer appear in the Recycle Bin, and now you're hoping to recover them and prevent this from happening again. I can relate the inconvenience this may have caused, not to worry, I will do my best to assist.
Here are some common causes:
Malware or third-party apps: Some apps or malware can delete files without your knowledge.
Storage limit exceeded: If your OneDrive is full, it may stop syncing or behave unpredictably.
How to Recover Deleted Files:
