Can’t use ‘bin/magento’ commands after running ‘composer update –ignore-platform-reqs’

I have magento running from https://github.com/markshust/docker-magento , everything is working fine, but when i run composer update --ignore-platform-reqs then all bin/magento commands stop working.

Any ideas on what could be happening? and what would be the best solution? Deleting the vendor folder from the container and running composer install --ignore-platform-reqs ?

Thanks!
