I have a lot problems with builds with this "internal error" too.
I have 2 websites, both gatsby
I tried both:
1) gatsby build
2) fully static files (gatsby build on my local computer) and only public dir added to github repo
Websites 10.000 files and 13.000 files
(small files 1kB to 300kB) html, css, js, png and webp
Sometimes my build is succefull for this 10.000 files website - like 1 of 5 tries
But most build tries fail when deploying:
06:58:47.583 Finished
06:58:48.061 Deploying your site to Cloudflare's global network...
07:18:07.790 Failed due to an internal error
