Hello @Rajeev ponuguma 

Description

It is often common to have flow designer execution with errors. Additionally, when there are other integrations involved such as the Mid Server, there is a requirement to run the flow again once the root cause of the issue is corrected.

After fixing the error, many users would like to run the flow designer again. 

Cause

Out of the Box,  there's no "rerun" feature in Flow Designer.

Resolution

There is an option to delete the currently executing/failed out flow context and then do an update on the parent record which will re-trigger the flow

Execute the startFlow() API as our documentation page FlowAPI - Scoped, Global states.

Our developer website has some examples about it

There are some examples, in ServiceNow Developer website

Plz Mark my Solution as Accept and Give me thumbs up, if you find it Helpful.

restartFlowContext();

function restartFlowContext() {

    // This variable tracks how many workflow contexts have been cancelled.
    var cancelContext = 0;

    // Get the sys_id of the current flow context record[sys_flow_context]
    var currentContextID = current.flow_context.getValue('sys_id');

    // Get the GlideRecord for the current flow context record[sys_flow_context]
    var currentContext = new GlideRecordUtil().getGR('sys_flow_context', currentContextID);

    // Check to see if the current flow context is already complete
    var isCurrentContextComplete = currentContext.state.getDisplayValue();

    // If the current workflow context is not already complete, cancel it before starting a new one
    // Note : Flow contexts do not cancel existing tasks when they are cancelled
    if (isCurrentContextComplete != "Error" && isCurrentContextComplete != "Complete" && isCurrentContextComplete != "Cancelled") {
        cancelContext = sn_fd.FlowAPI.cancel(currentContextID, 'This flow is being cancelled because it is being restarted via UI action on ' + current.number.toString());
    }

    // Get the latest version of the workflow being used in the current workflow context
    var newWorkflow = current.cat_item.flow_designer_flow.sys_scope.scope + "." + current.cat_item.flow_designer_flow.internal_name;
    
    // Generate a new flow context
    var inputs = {};
    inputs['request_item'] = new GlideRecordUtil().getGR("sc_req_item", current.sys_id.toString());
    inputs['table_name'] = current.getTableName();

    var newWorkflowContext = sn_fd.Flow.startAsync(newWorkflow, inputs);

    var contextId = newWorkflowContext != null ? newWorkflowContext.contextId : null;

    // Associate the new workflow context to the current record
    if (contextId) {
        current.flow_context = contextId;

        // Post a work note stating that the workflow context has been restarted
        current.work_notes = gs.getUser().getFullName() + ' has restarted the flow context for this record';

        // Update the record
        current.update();
    }

}

This is the code for a UI Action I created to restart a flow context in flow designer. It technically cancels the existing context and starts up a new one and re-associates it with the RITM.
