Downgrade the protobuf package to 3.20.x or lower.

To downgrade the protobuf package to version 3.20.x or lower, you can try the following steps:

1. Uninstall the current version of the protobuf package using pip:

pip uninstall protobuf

2. Install the specific version of protobuf that you want using pip:

pip install protobuf==3.20.0

This will install version 3.20.0 of the protobuf package. If you want a different version, simply replace "3.20.0" with the version number that you desire.

Once you have installed the desired version of protobuf, you can verify the installation by importing the package in Python and checking the version number:

import protobuf
print(protobuf.__version__)

This should output the version number of the protobuf package that you have installed.
