Ex 2016 Cu22 upgrade is now causing ELCLastSuccessTimestamp and get-serverhealth compliance errors

When running get-serverhealth checks on our on prem 2016 Exchange servers, after upgrading to cu22, I am now seeing compliance failures. Upon further investigation using the powershell command

Get-HealthReport -Server $server | where {$_.AlertValue -ne "healthy"} | fl

SerializationData       : {0, 1, 0, 0, 0, 255, 255, 255, 255, 1, 0, 0, 0, 0, 0, 0...}
RunspaceId              : 788647cb-a334-46ca-914e-2c28aa7f98ff
Server                  : nsc-dagc-06
State                   : NotApplicable
HealthSet               : Compliance
HealthGroup             : CustomerTouchPoints
AlertValue              : Unhealthy
LastTransitionTime      : 11/24/2021 10:04:15 AM
MonitorCount            : 43
HaImpactingMonitorCount : 0

and running

Get-MonitoringItemIdentity -Identity "Compliance" -Server $server | where {$_.Name -eq "ELC
MailboxSLAMonitor"}


SerializationData : {0, 1, 0, 0, 0, 255, 255, 255, 255, 1, 0, 0, 0, 0, 0, 0...}
RunspaceId        : 788647cb-a334-46ca-914e-2c28aa7f98ff
Server            : nsc-dagc-06
HealthSetName     : Compliance
Name              : ELCMailboxSLAMonitor
TargetResource    : Compliance
ItemType          : Monitor
Identity          : Compliance\ELCMailboxSLAMonitor\Compliance
IsValid           : True
ObjectState       : New

I then checked the Exchange logs and saw the following

Probe: {Compliance/ELCComponent_LastSuccessTooLongAgo} Mailbox guid: {xxxxx} In Org: {} Is archive: {IsArchiveMailbox = False} With stack trace: {The difference: 385.248046682816 days between today: 11/24/2021 12:24:19 PM and the date of last successful ELC run: 11/4/2020 6:27:07 AM for mailbox: e43093f4-01ae-4958-a4ad-75ca6b828392 is above the threshold: 7; Exception message: Microsoft.Exchange.Context.Core.SignalSignalTypeNotRegisteredException.} Get last ELC exception from Export-MailboxDiagnosticLogs -Component MRM then statistics with -ExtendedProperties and look at all ELC properties, specifically the value of ELCLastSuccessTimestamp. If mailbox is Archive use -Archive.

so I ran Export-MailboxDiagnosticLogs against the mailbox after using get-mailbox and the guid it gave

Export-MailboxDiagnosticLogs -Component MRM -Identity xxxxx

I can't find anything that tells me what code 399 is? Has anyone else seen this when upgrading to cu22? When I exported the mailbox diagnostic logs for that user (there are multiple mailboxes generating this on multiple servers with no obvious pattern) I did see

ELCLastSuccessTimestamp 11/4/2020 6:27:07 AM

when if the Manager Folder Assistant was working correctly on the mailboxes causing the compliance issue, the ELCLastSuccessTimestamp time stamp and date would be within 7 days of today. Could something be corrupted and prohibiting the MFA from checking this mailbox? This did not show up with the last cu, cu20.
