Getting weird error R4 wifi

Official Hardware Classic UNO R4 WiFi

I uploaded a sketch that does a bunch of stuff, what it does isn't important. I am just trying to mess around with the iot variables etc and the cloud dashboard. unfortunately, I get this error:

yeah trying to copy something from the IDE 2.x output window is very difficult. That was all I could get. There were a ton more of those addr: lines before this.

The weird thing is I did upload the game of life to it, but since then I have over written the sketch many times.

I have problems updating the firmware with this particular RF4 wifi board, and it doesn't look like I can't connect to the cloud with it.

I am wondering if this board may be defective.

HELP!

If any sketch uploaded made your boards unresponsive when you try to program it, try these steps:

  1. Restore the USB connectivity firmware on UNO R4 WiFi with espflash
  2. Update the connectivity module firmware on UNO R4 WiFi . This is required to connect to wifi network and the cloud.
  3. Ensure that you use 2.4Ghz wifi with the SSID and Password not too long and does not contain special characters.
  4. Use a simple sketch to test first, like https://app.arduino.cc/templates/cloud-blink

Thanks I got it fixed. I just wanted someone to know that new boards from Arduino need to be updated and it took me 6 tries before it finally was successful. Each time the USB bridge needed to be reflashed.
