I have encountered the same issue. First please try to check your current version of packaging

pip list | grep packaging

if the version of packaging is <22.0, please upgrade it to 22.0

pip install packaging==22.0

Then, remove log, build and install folders in the workspace and colcon build again. Hope this can help you to fix this issue too.
