Beanstalk console cannot pick arm64 options

Using AWS console to create a new environment of an elastic beanstalk app, I cannot select arm64 instances anymore. When I do so, the console automatically applies as default instance types "t3.micro" which is not a valid arm64 instance type and the call to AWS console backend servers for configuration options fails, making the select not update.

{"__type":"com.amazonaws.elasticbeanstalk#ConfigurationValidationException","message":"Configuration validation exception: Invalid option specification (Namespace: 'aws:ec2:instances', OptionName: 'InstanceTypes'): Your selected instance types (t3.micro) aren't available in your selected VPC Subnets. . Please check your VPC Subnets."}

I have never created an env using the AWS CLI and I cwould like to avoid, has anyoene a workaround?
