2022 Server randomly requires reboot due to "The RPC server is unavailable." error

I have a 2022 Server that randomly (usually once daily, no specific time) stops allowing RDP and local logins. It throws an RPC server is unavailable error. Any one still logged in remains in, though they are unable to reset/shut down the server. When attempting to do so via cmd prompt it returns RPC error as well. Any new login get the error after typing in user/PW. Doesn't matter if it's a domain or local account. Only way to get past this is a hard reboot.

After the reboot things return to normal and logins happen just fine. This is a VM running in Nutanix AHV. Things I've tried so far:

Upgrade VirtIO driver

Checked DNS

Checked Time

RPC service is running
Remote Registry isn't running, but it is set to auto start (triggered). Checked other working servers and it was set to this.

Checked this page from MS

UPDATE:

To save everyone some reading, there appear a common factor between a lot of the community. Sentinel1. Some users are reporting uninstalling it has fixed there issue. Others are downgrading versions.

    Any chance this started after installation of 07-24 Cumulative update?

    So after more than a month of daily problems the issue has resolve itself. It's been 8 days now with no issues. This is a head scratcher as no updates were applied, no settings changed. The only thing that happened was a hard reboot which happened daily to get access back.

    We've started experiencing this on a few systems in the last couple of weeks as well. Local session manager crashes then we get the 'RPC server unavailable message' requiring a reboot to restore login. Do you have SentinelOne installed on the systems having this issue?
