          This is caused by an invalid Jenkins configuration where the matrix-auth plugin is not installed, disabled, or otherwise not loadable, while it is required to load the Jenkins configuration.

          The log will tell you why the plugin is unloadable, if that's the problem here.

          While the experience here isn't great, there's no sign of a bug here.
