Azure App Service deployment intermittently fails for different reasons

I have a Next.JS application, that I'm deploying to an Azure App Service. I'm using the VSCode Azure extension tool (as I never got the github action working)

When I deploy this App, it intermittently fails for no obvious reason. For example, I deployed 2 days ago (successfully), then made some small changes to the app (just to the layout), and tried to re-deploy, but it failed. If I look at the deployment logs, they just stop with no error message.

I have compared the log from a few days ago, to the one I've just tried, and there are some variations.

The one that failed, had this at the top - notice that it says "Version 20.18.0 of platform nodejs is not installed", but on the one that worked, it doesn't mention this..

And then the build that succeeded, appears like this

...it then continues, and succeeds
