After rebuilding app, can't sign in with error 500

- git clone https://github.com/discourse/discourse-bcc.git
# - git clone https://github.com/paviliondev/discourse-landing-pages.git

After rebuilding, error 500 persists.
It’s weird that this time safe mode didn’t save me. In backtrace I’ve noticed chat, can it be a chat bug? How can I disable chat plugin temporarily to test?
