Unity Building Linux Il2CPP player requires a sysroot toolchain package to be installed

For some reason I'm unable to build an IL2CPP Linux build in unity. I used to be able to build IL2CPP Linux builds fine on the same machine using the same version of unity, but it recently stopped working. This problem occurs in a new project, so I think that this problem doesn't have to do with the project itself. Unity 2021.3.0f1 LTS (Apple Silicon build) macOS Monterey 12.2.1 https://i.stack.imgur.com/VzBOD.png
