Hiero: protobuf TypeError

[jeangjenq]

Describe the bug
3.12.0 to 3.14.0 updated protobuf from 3.19.4 to 4.21.5 caused TypeError when launching NukeStudio.

File "C:\OpenPype\.venv\lib\site-packages\google\protobuf\descriptor.py", line 755, in __new__
    _message.Message._CheckCalledFromGeneratedFile()
TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

To Reproduce
Steps to reproduce the behavior:

1. Upgrade from 3.12.0 to 3.14.0
2. Launch NukeStudio from Launcher.
3. Get NukeStudio init.py error pops up. Scrolls down on NukeStudio console to see the error above.

Expected behavior
NukeStudio launch without errror.

Screenshot

Desktop (please complete the following information):

• OS: Windows 10 Pro 21H2
• Host: NukeStudio

Additional context
Setting environment variable
PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python
like the error recommended helps. But as it suggests python parsing will be much slower.

But as it suggests python parsing will be much slower.

Is this an effect you notice in day to day usage in Nuke? I am not sure where it's used whether it'd be an urgent issue or not.
