One solution is simply to not put files that you will be using with the Arduino IDE under OneDrive.

If you do want to continue using OneDrive, the problem has been resolved in the beta build of the Arduino IDE:
https://www.arduino.cc/en/Main/Software#beta
you should be aware that the beta build is primarily intended for beta testing and you will be more likely to encounter bugs than you would using a stable release of the Arduino IDE.

For more information and other workarounds for the problem see:
