I'm investigating a build with this warning from RAR:

/Users/builder/azdo/_work/1/s/main/build/tools/MSBuild/bin/Microsoft.Common.CurrentVersion.targets(2143,5): warning MSB3246: Resolved file has a bad image, no metadata, or is otherwise inaccessible.

This exception is thrown in four places:
https://source.dot.net/#Microsoft.Build.Tasks.Core/AssemblyDependency/BadImageReferenceException.cs,cbeccdcba5e80a17,references

It could be a BadImageFormatException, FileNotFoundException, FileLoadException or any other IORelated exception. We throw away the callstack and don't display the type of the underlying exception. We should print the original exception ToString() not just the Message.
