Stalled on "Loading Application..."

Meadow Development
1

I am attempting to run the HelloMeadow project (right from the Template) on a new Meadow device, but the first Deployment I get the following error, then following deployments get stuck on “Loading Application…”. I can’t find any errors or logs. All the latest versions of everything used (VS, Meadow, Nuget, etc) have been loaded.

I followed the Trace steps in another thread and here is the output for MonoEnable

Guessing it has something to do with the missing config file. Any clues or insight would help.

I was told that it goes back to default settings if no config is found. Can you do one more run with meadow --MonoEnable --KeepAlive?

I tried, but the same result. I ended up flashing everything and running the Step 4 in the Max directions:

meadow --MonoUpdateRt
meadow --FlashEsp
meadow --MonoEnable

And I was able to get it deployed. Cheers for reaching out.
