Blueprint manager wont load in

hey quick question i installed the plugin in oxid plug in folder( this by the way is on a server hosting site)
but when i go to rebot server in the system coman i keep getting an error of it being currupted and tell me to check it on https://jsonlint.com/ which i do and it keeps saying the first four lines are wrong

using System.Collections.Generic;
using System.Linq;
using Newtonsoft.Json;
using UnityEngine;

error i get ---

Error: Parse error on line 1:
using System.Collect
^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'


what can i do to fix this

Dont edit `.cs` file
