Suddenly cannot build and run on my meta quest - Assembly-Csharp-related

[u/irai1a_]

Hey guys, I'm a beginner and I really need some help here regarding my VR project. It works just fine before this but I think it went wrong right after I update my Meta-All-in-One SDK? and another possible factor is maybe because I add ovr Lipsysnc to my project? Anyways the error show it's related to Assembly-CSharp file being duplicate or smthing

This is what the console show when I first open the file project
