Hello, this morning my Discourse failed for me mid-usage, and rebuilding has me stuck. Initially I had the “Oops!” page, but after my first rebuild it won’t start at all.

- I’ve removed _all_ plugins, official or otherwise, leaving only `docker_manager.git`
- I’ve `git pull`ed from within `/var/discourse` and am `Already up-to-date.`
- I’ve tried `./launcher cleanup`, but `./launcher rebuild app` still fails

The error shown is:

```plaintext
FAILED
--------------------
Pups::ExecError: cd /var/www/discourse && su discourse -c 'bundle exec rake assets:precompile' failed with return #<Process::Status: pid 17092 exit 1>

**FAILED TO BOOTSTRAP** please scroll up and look for earlier error messages, there may be more than one

```

Going up, I see a `rake aborted!` error:

I gather there may be a theme and/or component error, but I cannot enter [safe mode](https://meta.discourse.org/t/53504?silent=true) to disable anything because my site won’t start at all.

What do you recommend to do next in this scenario?

Thank you.
