I'm dealing with a problem on one of my Windows Server 2019 Hyper-V Failover Cluster nodes. The Cluster Service keeps stopping and restarting, which prevents the node from rejoining the cluster and leads to quarantine states. I'm using BitLocker with Cluster Shared Volumes (CSV). According to the Microsoft article for KB5062557, I'm supposed to reach out to Microsoft Support for help, but it seems I don't have an eligible support plan linked to my account. I'm concerned about trying a rollback since I've heard that many administrators have faced ongoing problems with manual recovery methods, including service restarts and re-adding nodes, which only seem to give temporary relief. Has anyone been in a similar situation? What steps is Microsoft Support advising?

A customer I know tried a private fix from Microsoft Support, but it actually made things worse—the node lost access to the cluster volume entirely. We opened another support ticket but haven’t heard back in two days. Right now, we’re planning to migrate everything to a 2022 cluster and might just scrap the 2019 one altogether. Just so you know, you can open a support ticket for a fee, and if it's Microsoft's fault, they usually refund that cost. We were told we would get our money back since it’s a code bug.
Have you checked the Microsoft Update Catalog for KB5062557? You can search for it here: https://www.catalog.update.microsoft.com/Search.aspx?q=KB5062557. If you don’t have a support agreement, try going to the Contact Us portal after following the self-help steps. Make sure to log in with a valid Microsoft Live ID to access the Support For Business Services Hub. Here's the link you can use: https://support.microsoft.com/en-us/contactus?ContactUsExperienceEntryPointAssetId=S.HP.SMC-HOME.
This first reply felt a bit off to me; it seemed more like a bot response. I don't think searching for a KB helps when I really need support with the issues caused. The Microsoft Support guidance just led me back to the Service Hub, which I can't access without a support contract. If anyone has tips on how to deal with responses like this, I'd love to hear them!
