This commit appears in #13824 which was approved by eviltrout. It was merged by nlalonde.

@nlalonde the latest discourse ver on Installed 2.8.0.beta4 ( 0e53769f71 ) that we upgraded on to from GUI (updated fine) and then did we rebuild from terminal, after rebuilding, our site is broken and crashing forever, its not loading at all. more details here Discourse updated from admin, not working after rebuild. Fatal error, site does not load anymore after rebuild - support - Discourse Meta

There is likely some fatal bug which is causing sites to break and never load after rebuild, i think this bug came in some commits and files updates you guys did on 14th or 15th aug 2021.

Please let us know once this is fixed so we can try a rebuild and hope our site does not break again.
