Description
After incorrect upsert operation (incorrect syntax, no value for PK in query) SDK seems to be unable to establish the connection with immu db after application restart. It fails with exception:
```c#
ImmuDB.Exceptions.VerificationException: 'Data is corrupted (dual proof verification failed for the local state).'
```
Immuclient shows no error and has no troubles to connect to that db and successfully operate with its data though.
Environment:
Windows 10, Visual Studio 2019
Console Project on .NET 5
ImmuDB4Net 1.0.5
ImmuDB Server, Client and Admin 1.5.0

Research direction
Start by reproducing the incorrect UPSERT in the .NET 5 console project, then restart the application and compare SDK reconnection behavior with immuclient against the same immudb database. Investigate the VerificationException and dual proof verification failure; done means an invalid UPSERT no longer prevents the SDK from reconnecting after restart.
