'Errors when build unity proejct for Macos on Windows

When I want to build a macOS version of my Unity project, I get following errors. But When I choose to Build Winows Version, it goes very well. Can someone help with this problem?

Many Thanks.

My version of Unity package is 2020.3.18f1c1 and my computer is Windows
