@NM Thanks for posting in our Q&A.
For this issue, it is suggested to try the following steps to troubleshoot:
1.Confirm that the Profile Configuration settings are correct. This is the most common problem area. Make sure that Certificate Authority and Certificate Authority Name are correct.
2.Check NDESConnector_Date.svclog on the Intune Certificate Connector computer for errors. By default, this is found in C:\Program Files\Microsoft Intune\NDESConnectorSvc\Logs\Logs.
3.Check the MS Certificate Authority for errors. Specifically, check the Failed Requests folder and look for errors
4.Check the C:\Program Files\Microsoft Intune\PfxRequest folders for any failed or stuck processing PFX requests.
