Cannot Publicly Share CloudWatch Dashboard

I have a dashboard that is made up of alarms from different subaccounts, and when attempting to share it throws error on the "Accept Policy and Generate Shareable Link": page: "An error happened trying to share your dashboard"

Cloudtrail shows this error: }, "eventTime": "2022-02-25T15:16:14Z", "eventSource": "iam.amazonaws.com", "eventName": "CreateRole", "awsRegion": "us-east-1", "sourceIPAddress": "x.x.x.x.x", "userAgent": "Coral/Netty4", ** "errorCode": "InternalFailure", "errorMessage": "CreateRole operation failed",** "requestParameters": null, "responseElements": null, "requestID": "e25fb6da-ffca-4d9f-b1d2-0e6c2xxxxxx", "eventID": "301acbbf-fcf2-479b-a6fd-7b70axxxxxx", "readOnly": false, "eventType": "AwsApiCall", "managementEvent": true, "recipientAccountId": "12345678910", "eventCategory": "Management" }
