Gossamer fails to produce blocks using runtime v0.9.43: `mandatory dispatch error`

## Describe the bug

- After upgrading the runtime specs to v0.9.43 (PR: https://github.com/ChainSafe/gossamer/pull/3353) gossamer is facing a problem while producing blocks:

```

```

### More informations
While applying a mandatory extrinsic and it fails the runtime returns the mandatory dispatch error, an extrinsic is mandatory if it is an inherent extrinsic
