Azure Cosmos Db Emulator starting but never start

I use Azure Cosmos Db Emulator for about 1 year now and it’s the 3de time it sudently stop working.

The only way i found for resolve the problem was to do a complete re-install of windows 10 …

My configuration :

• Windows 10 Pro
• Administrator privilege
• Domain link to AAD
• Antivirus software : ESET Endpoint antivirus 9.1.2051.0
• Intel(R) Core(TM) i5-4670 CPU @ 3.40GHz 3.40 GHz
• 32 Go of RAM
• All my software installed on C :

I try this in command prompt (as Administrator) :

1. Clear performance counter before start

• Microsoft.Azure.Cosmos.Emulator.exe /shutdown
• lodctr /R (2 time to be sure)
• Microsoft.Azure.Cosmos.Emulator.exe

Result :

• The notification for « Starting » show up
• A dump file is create in AppData/Local/CrashDumps
• The notification that the emulator is « start » never come
• The web page never open

2. Uninstall – re-install

• Microsoft.Azure.Cosmos.Emulator.exe /shutdown
• Delete folder AppDataLocalCosmosDBEmulator
• Uninstall Cosmos Db Emulator
• Delete folder C:Program FilesAzure Cosmos DB Emulator
• Restart the computer
• Install last app version : azure-cosmosdb-emulator-2.14.9-3c8bff92.msi
• Check for start the emulator after install end

Result :

• Same result than 1)

3. Start trace

-   Microsoft.Azure.Cosmos.Emulator.exe /shutdown
-   Microsoft.Azure.Cosmos.Emulator.exe /startwprtraces
-   Microsoft.Azure.Cosmos.Emulator.exe
-   [wait for 1 minute]
-   Microsoft.Azure.Cosmos.Emulator.exe /stopwprtraces
-   Microsoft.Azure.Cosmos.Emulator.exe /shutdown

Result :

• The notification for « Starting » show up
• A dump file is create in AppData/Local/CrashDumps
• Until the 1 minute of waiting , a dump file was created for about every 20/30s
• When i execute Microsoft.Azure.Cosmos.Emulator.exe /stopwprtraces, a docdbemulator_001.etl was created in C:Program FilesAzure Cosmos DB Emulator
• The notification that the emulator is « start » never come
• The web page never open

I try to read the dump file with WinDbg.exe and i found this error message :

CLR_EXCEPTION_System.Collections.Generic.KeyNotFoundException_80131577_Microsoft.Azure.Documents.Common.dll!Microsoft.Azure.Documents.Common.Service.WindowsFabricConfigurationProvider.GetValue

And the stack trace was :

In windows logs I found the same error description (in french):

Application : Microsoft.Azure.Cosmos.Compute.Host.ServiceFabric.EntryPoint.exe Version du Framework : v4.0.30319 Description : le processus a été arrêté en raison d'une exception non gérée. Informations sur l'exception : System.Collections.Generic.KeyNotFoundException à Microsoft.Azure.Documents.Common.Service.WindowsFabricConfigurationProvider.GetValue(System.String) à Microsoft.Azure.Documents.Common.CrashDump.Register(System.Collections.Generic.IEnumerable`1<System.String>, Microsoft.Azure.Cosmos.Core.IConfigurationProvider) à Microsoft.Azure.Cosmos.Compute.Host.ServiceFabric.EntryPoint.EntryPoint.CosmosDBGatewayInit(System.Fabric.CodePackageActivationContext, System.String) à Microsoft.Azure.Cosmos.Compute.Host.ServiceFabric.EntryPoint.EntryPoint.Main(System.String[])
