Getting error: Lightroom was not able to prepare the selected file at .... for edditing.

What type of drive is F:? When it is a external hard drive is it connected?

Do have lightroom full access to the appropriate drive/folder?

What has been changed on your system before the error occur?

What you can try is to reset the preferences to the default settings. 

Reset Procedure: 

• Close Lightroom. 
• Windows: Hold down [Alt]+[Shift] while restarting Lightroom. 
  Mac: Hold down [Opt]+[Shift] while restarting Lightroom. 
• Overwrite the Preferences when prompted by the dialog. 
• Close Lightroom. 
• Restart Lightroom. 

It's recommended to backup your preferences before you reset the preferences to the default settings:
