I think "com.unity.nuget.newtonsoft-json" conflicts with "jillejr.newtonsoft.json-for-unity." The errors disappeared after removing jillejr.newtonsoft.json-for-unity.
But Netwonsoft Json Unity Package document says "This is a package intended for internal Unity Development Projects and as such this package is not supported. Use at your own risk."
Is there a way to use "jillejr.newtonsoft.json-for-unity" instead of "com.unity.nuget.newtonsoft-json"?

 

Thanks for the reply! I am using it in the player. it's fine if I am safe to use it
