### Describe the bug

Attempting to deploy a working solution to Azure Container App using aspire deploy consistently fails. The AppHost process exits prematurely, and the CLI cannot establish a backchannel connection.

### .NET Version info

dotnet --info
.NET SDK:
Version: 10.0.102

Workload version: 10.0.100-manifests.e5d3dea4
MSBuild version: 18.0.7+445250245

### Anything else?

aspire: 13.1.0+8a4db1775c3fbae1c602022b636299cb04971fde

Start with the AppHostCliBackchannel connection and DotNetCliRunner exit reported in the log, using the stated .NET SDK 10.0.102 and Aspire 13.1.0 versions. Reproduce with a simple Azure Container App deployment; done means the AppHost remains running long enough for the CLI to establish its backchannel and the deployment completes.
