Skaffold not working with Helm 4 (using Rancher Desktop 1.22)

[SSchwaiger]

I've freshly installed Rancher Desktop with bundles Helm v4.0.5. Trying to deploy a helm chart using Skaffold fails.
Note: replacing the helm binary that comes with Rancher Desktop with a v3.x version makes Skaffold work again.

My first try was a simple "skaffold dev" command in a non-admin shell. This led to the following error:

deploying "default-blueprint": Failed to install Helm plugin: Installing plugin from local directory (development mode)
Error: symlink C:\Users\<redacted>\AppData\Local\Temp\skaffold-render1032218029 C:\Users\<redacted>\AppData\Roaming\helm\plugins\skaffold-render1032218029: A required privilege is not held by the client.

So I tried running the command in an administrative shell. Unfortunately without luck, but with a different error:

Go to Settings, search for "Developer Mode" and enable that:

How does this help? Where is this toggle? Windows Settings? Rancher Desktop Settings?
Sorry, I don't get the point here...
