I'm sorry that I cannot run make html success.
The giza version is unknown, if I use the latest version(0.5.18), then I need Pygments>=2.12.0, which required Python>=3.6. If I use giza-0.5.10, I got this error in giza.log:

ERROR:giza.pool:caught error "('key "images" in configuration object (<class \'giza.config.paths.PathsConfig\'>) is not defined', "'PathsConfig' object has no attribute 'images'")" in migrating source to build/DOCS-16062/source <function transfer_source at 0x7fb16b510e50>, waiting for other tasks to finish
