Fix .NET Core 2.0 Web API Version Mismatch

I need a skilled .NET/.NET Core 2.0 expert to urgently fix my web API's assembly version mismatch issue. The problem originates from the System.Numerics.Vectors assembly and was first noticed after a recent update but even after undoing the updates the issue exists. There's also a complication: my project utilizes a couple of third-party libraries like docentric for document generation.

One more challenge is same web api in a different IIS application on the same server is working fine.

Actual Error Message is below:
Could not load file or assembly 'System.Numerics.Vectors, Version=4.1.4.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The located assembly's manifest definition does not match the assembly reference

Key Skills Needed:
- Expertise in .NET/.NET Core 2.0
- Proficient with Web API
- Experience troubleshooting assembly version mismatches
- Familiarity with System.Numerics.Vectors
- Knowledge of third-party libraries integration

Conditions:
-The work must be completed through remote access during Indian Standard Time (Day-Shift).
-Payment will only be made after the task is successfully completed.
