Hello!

I have trouble running the preview command.
First, I run the build command:

doc-builder build transformers docs/source/en/ --build_dir ~/tmp/test-build

Afterwards, I run:

doc-builder preview transformers ~/tmp/test-build

Which leads me to the following prompt:

Building the MDX files:  31%|█████████████████████████████████████████████▌                                                                                                       | 79/258 [01:53<19:06,  6.40s/it]

And this process would take infinitely long, it didn't even finish after 8 hours. I am not sure whether this is expected or some bug.

NB: it gets stuck at around 77/258, before this everything is super fast.

I am running M1 Mac OS.

Thanks!
