Service Fabric Deploy error

Question

We upgraded the application from multiple versions to 3.1 .NetCore. Encountered couple of issues in the process, and the latest is happening when deploying to Cluster on cloud.
total 3 applications, 2 apps have 7 services each and 1 has web api service.

Out of these, the web api, and total 3 services from 14 services across 2 apps are failing. 2 more were failing, but started working after downgrading the Microsoft IdentityClient to 3.14.2

one of the errors is 'System.RA' reported Warning for property 'ReplicaOpenStatus'.
Replica had multiple failures during open on _Primary_1. API call: IStatelessServiceInstance.Open(); Error = System.InvalidOperationException (-2146233079)
ServiceEndpoint not found in Service Manifest.

Answer 1

https://learn.microsoft.com/en-us/answers/questions/26497/service-fabric-actors-unable-to-create-replicas.html using this as example, I downgraded the DLL's to 4.0.470. Still same error

Answer 2

I checked the servicemanifest and it has the endpoints, the transformed files are present

Then, the other error is
System.Hosting' reported Warning for property 'CodePackageActivation:Code:EntryPoint:132679177342412731'.
There was an error during CodePackage activation.The process/container terminated with exit code:2147516556. Please look at your application logs/dump or debug your code package for more details.
