I have this error while connecting emulator

Error from Companion: invoke: no method named `AppName' in class edu.mit.appinventor.aicompanion3.Screen1

screen1.scm as below:
#|
$JSON
{"authURL":[],"YaVersion":"216","Source":"Form","Properties":{"$Name":"Screen1","$Type":"Form","$Version":"30","Uuid":"0","Title":"Screen1","AppName":"Youssef"}}
|#

The AppName property is fairly old, but not as old as the default companion bundled with the emulator. Did you dismiss the prompt that said you had to update the companion app in the emulator when it first connected?

Hi,
It didn't ask me for any update
