Downgrading isn’t supported, you can’t roll back to beta or stable until they pass the current tests-passed. You can use the commit ID as per [this topic](https://meta.discourse.org/t/change-tracking-branch-for-your-discourse-instance/17014), but it’s very unlikely a routine upgrade is the cause - Discourse _isn’t_ prone to spontaneous combustion.

Do you have sufficient free space on the server? Have you disabled all plugins and re-tried?
