Describe the bug

We have a WinUI Desktop application with a class library, but when we try to build it, we get the error "Unable to copy class library files (used .xaml or.txt files) files when compiling WinUI Desktop project." It occurs as a result of accessing files with long file paths and running projects in long directories. The reported issue does not occur if I move the project location closer to the root directory. Can you please confirm whether this is a bug or expected behavior in WinUI? If this is a bug, any suggestions for a workaround would be greatly appreciated.

Please find the issue details below.
