Build Failed with 4 Errors,Unity Build Failed With 4 Errors

Hi! I tried building my game today, however, it didn't work. I built my game before, but it was in a separate project. It came with a long error (at the bottom of the question) I've already done some research but concluded with no solution, does anyone know why and how to fix this issue? Thanks! :) *UnityEditor.BuildPlayerWindow+BuildMethodException: 4 errors at UnityEditor.BuildPlayerWindow+DefaultBuildMethods.BuildPlayer (UnityEditor.BuildPlayerOptions options) [0x002da] in <4e64905d831f4883a53259ef37fb023b>:0 at UnityEditor.BuildPlayerWindow.CallBuildMethods (System.Boolean askForBuildLocation, UnityEditor.BuildOptions defaultBuildOptions) [0x00080] in <4e64905d831f4883a53259ef37fb023b>:0 UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)*
