We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
protobuf dependency compatibility
* Python: 3.5
* OS: osx
* `import web3` output

```
ContextualVersionConflict
```

### What was wrong?

[protobuf](https://github.com/ethereum/web3.py/pull/1493) compatibility needs updating. Needed to downgrade protobuf to get it working. Version currently needs to be >4 but protobuf's latest version is 4.21.6

### How can it be fixed?

The newest version of protobuf should be compatible https://pypi.org/project/protobuf/
