dotnet workload restore - Source array was not long enough

[krwq]

Describe the bug / Repro

I'm trying to build dotnet new android project which was generated using net9 and changed TargetFramework to net10.0-android. When I built I got following error:

To build this project, the following workloads must be installed: wasi-experimental
To install these workloads, run the following command: dotnet workload restore

When running dotnet workload restore on that project I'm getting another error:

Installation rollback failed: Source array was not long enough. Check the source index, length, and the array's lower bounds. (Parameter 'sourceArray')
Workload update failed: Source array was not long enough. Check the source index, length, and the array's lower bounds. (Parameter 'sourceArray')

Further technical details

@joeloff @marcpopMSFT seems to be the same as #45632. Is workload installation broken in 10.0?

[marcpopMSFT]

Workloads should be working in 10 now though I don't know if all of the maui side baselines have been updated yet. @jonathanpeppers

[jonathanpeppers]

We could update .NET 10 baselines, when we branch for preview 1. They wouldn't be the "final" ones, but that might improve things for now?

Note the Android workload listed above does not support .NET 10:

I technically used a slightly different version of the SDK (current main), but I had a quite different experience:

Maybe there's a difference if I can find that package? But I'm not sure where to find that, as it isn't on nuget.org, as far as I can tell.
