Failover Cluster

Dears

We upgraded our environment from Windows Server 2012 R2 into Windows 2019

Everything seems to work normally except for Windows Failover Cluster Service

The service is not able to run at all with the event id1090

We removed the failover cluster feature and re-add it again; however, the problem persists

Please advise

Thank you
