We're pushing fairly large changes once a week from multiple team members. What has really helped is having comprehensive unit, integration and end-to-end tests. We run first 2 on every check-in into main branch. Then run all 3 after moving from QA to Staging. And finally do smoke tests in Staging. The only problem with this approach is of course spending ungodly amount of time writing tests and infrastructure/tooling to support automated tests especially end-to-end. But this hasn't failed once yet.
