# Disable Assembly Validation

If you ever get an error that looks like this, disable the Assemble Version Validation in `Project Settings` > `Player` > `Other Settings`.

{% code overflow="wrap" %}

```
Assembly 'Assets/Convai/Plugins/Grpc.Core.Api/lib/net45/Grpc.Core.Api.dll' will not be loaded due to errors: 
Grpc.Core.Api references strong named System.Memory Assembly references: 4.0.1.1 Found in project: 4.0.1.2.
```

{% endcode %}

Ensure that Assembly Validation is disabled in `Project Settings` > `Player` > `Other Settings`.

Restart the Unity project after unchecking the box should fix the issue.
