I tired to remove application access to the users from the User Interface by using Microsoft graph API and Azure AD graph api i used following azure AD graph api

https://graph.windows.net/tenantid/users/{userId}/appRoleAssignments/{appId}?api-version=1.6

You may be getting this error because you are trying to delete the application access using AppId of the application. Please make sure to use "AssignmentID" from Azure Portal which is unique ID of the specific role assignment and links the user/group and the service principal object. Go to Azure Active Directory > Users > Select specific User > Applications > Select any application to navigate to "Assignment Details" blade.

See screenshot below -

enter image description here

This unique id is also available as "ObjectID" if querying application role assignments through Graph API -

https://graph.windows.net/{TenantID}/users/{UserID}/appRoleAssignments

Here is the sample output of the above API call.

"odata.metadata": "https://graph.windows.net/sasharms.onmicrosoft.com/$metadata#directoryObjects/Microsoft.DirectoryServices.AppRoleAssignment",
"value": [
    {
        "odata.type": "Microsoft.DirectoryServices.AppRoleAssignment",
        "objectType": "AppRoleAssignment",
        "objectId": "r7rDMrnDo0uCuwnosRwwzuziiF5B8s9FnsotYya5DMU",
        "deletionTimestamp": null,
        "creationTimestamp": "2018-05-10T14:10:49.8197813Z",
        "id": "00000000-0000-0000-0000-000000000000",
        "principalDisplayName": "SaurabhSharma",
        "principalId": "32c3baaf-c3b9-4ba3-82bb-09e8b11c30ce",
        "principalType": "User",
        "resourceDisplayName": "WebAppOpenIdGraphApi",
        "resourceId": "90658e39-2559-48fb-a27a-5e50cca94288"
    }

This Id is ideally used for performing various operations against the application using any programmatic interfaces like PowerShell and Graph APIs.
