Reproduction Steps

from aws_cdk import aws_config as compliance
from aws_cdk import  Stack,

class ComplianceStack(Stack):
    def __init__(
        self,
        scope: Construct,
        construct_id: str,
        **kwargs,
    ) -> None:
       

        compliance.ManagedRule(
            self,
            "VPC FLOW LOGS",
            identifier=compliance.ManagedRuleIdentifiers.VPC_FLOW_LOGS_ENABLED,
            maximum_execution_frequency=compliance.MaximumExecutionFrequency.TWELVE_HOURS,
        )

The code you gave does not reproduce the issue for me. The stack synths fine.

[bearrito]

That's a slightly reduced version than what I using in production. I'll see if I can create smaller stack that reproduces it.

[bearrito]

I can't reproduce this either now. I'll say that I updated CDK versions after filing this ticket, perhaps there was a fix in there.
This is probably okay to close.
