file explorer crashes when dropping a file to OneDrive

Hi Paul Chou,

I'm here to help with your query on the Microsoft Q&A forums. Apologies for any inconvenience you are experiencing.

Thank you for sharing the details of your experience. I understand how frustrating it can be when File Explorer crashes while working with OneDrive, especially when you’re just trying to overwrite a file. Let me give you an explanation of why this might happen and how to fix it.

• Some Windows Insider Preview builds have encountered File Explorer crashes during OneDrive operations like overwriting files.
• If OneDrive is actively syncing or indexing the file, overwriting it can cause Explorer to hang or crash.
• Occasionally, a mismatched or outdated OneDrive version can lead to instability.

Here are some initial troubleshooting steps that you should try:

1 - Restart your device first – This often clears temporary locks and sync issues.

2 - Check for Windows Update - Install the latest Insider build and cumulative updates.

3 - Reset or Reinstall OneDrive

• Run these command lines in cmd.exe (run as Admin)
  • Stop OneDrive: taskkill /f /im OneDrive.exe
  • Uninstall: %SystemRoot%\System32\OneDriveSetup.exe /uninstall
• Then reinstall using the latest installer: Download OneDrive

You can also try the alternative methods below:

• Disable Preview Pane in File Explorer – This reduces crashes caused by file previews.
• Optional: Enable “Launch folder windows in a separate process” in Explorer options for better isolation.

I look forward to receiving your update. Let me know which solution works for you or if your problem persists and you need further assistance, feel free to ask me by clicking "Add Comment". Thanks for your effort.
