Division by zero - TSynchronizeProgressForm::CalculateProgress

This error appears when I try to synchronize a folder. From the first failure, it continues to fail in this folder but not in the others

WinSCP 5.16

Error message:

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

Thanks for your report.
