Welcome to the forum, @fkaute.
I suspect you're facing the same issues as another user did recently.
Let's check a couple of things.
Ensure that Trust Manager's "trust-namespace" value is set to the same namespace where the Ziti Controller is installed, because that's where the certificates are located from which Trust Manager will compose the Bundle resource.
The error message you shared points to the Bundle that provides CM ziti-controller-ctrl-plane-cas not being available, which would normally be pending until Trust Manager is able to source the necessary certs.
You can diagnose this by describing the Trust Manager controller and following the TM log.
Another thing to check is that Helm's wait option is false, which is the default for the CLI, but some wrappers like the Terraform Provider set it to true by default, which prevents the life cycle hooks from triggering.
