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.

enter image description here

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!
