I am trying to create a Google Cloud Composer instance. Composer V1 has ended support. So, only option is to create with V2 which is where its failing due to below error.

Configurations used:
GCP Account Type: Free trial

Composer version: composer-2.8.1-airflow-2.7.3

Environment sizes tried: Small, medium, large, custom

Location: us-central1

Custome Env Size config:
Scheduler: 1 scheduler with 1 vCPU, 2 GB memory, 1 GB storage
Triggerer: 1 triggerer with 1 vCPU, 1 GB memory, 1 GB storage
Web server: 1 vCPU, 2 GB memory, 1 GB storage
Worker: Autoscaling between 1 and 3 workers, with 1 vCPU, 2 GB memory, 1 GB storage each

Error:
CREATE operation on this environment failed 2 days ago with the following error message:
Some of the GKE pods failed to become healthy. Please check the GKE logs for details, and retry the operation.

I did further checked the GKE logs and under workloads, found the pods are unschedulable but i am not able to understand the exact cause. Even the logs does not show any detailed error.
I tried with multiple times for retry but every time its failing with same error.
I want to launch the composer instance
