Restart com.hmdm.launcher after update

Question

Hello!
I have custom build hmdm-android. I increase versionCode and versionName and make new build. After installing the new apk version HMDM Launcher(Agent) from backend server, the Agent does not start automatically (you can start it manually). Device owner rights is set.

The com.hmdm.emuilauncherrestarter application is installed and running.
LogCat:
E Failure starting process com.hmdm.launcher
java.lang.SecurityException: Package com.hmdm.launcher is currently frozen!

To restart Headwind MDM launcher after updating, we use the "Launcher Restarter" app (package ID: com.hmdm.emuilauncherrestarter).

Make sure this application is included in your configuration, and the "Launcher Restarter" app is installed.

Here's the related error description: https://stackoverflow.com/questions/47643030/android-security-exception-package-is-frozen  Probably this could help you resolving the issue.

Headwind restarter included and working. It try to restart launcher, i see ""Starting Headwind MDM Launcher!" in logcat. Forgot to say, i use Android 10. This behavior is observed on two devices. If i modify emuilauncherrestarter and leave only one function call for example
guaranteedStartHandler.postDelayed(runnable, 10000);
I see in logcat
ActivityTaskManager     system_server                        W  Background activity start [callingPackage: com.hmdm.emuilauncherrestarter; callingUid: 10074; isCallingUidForeground: false; isCallingUidPersistentSystemProcess: false; realCallingUid: 10074; isRealCallingUidForeground: false; isRealCallingUidPersistentSystemProcess: false; originatingPendingIntent: null; isBgStartWhitelisted: false; intent: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 pkg=com.hmdm.launcher cmp=com.hmdm.launcher/.ui.MainActivity }; callerApp: ProcessRecord{e6d0576 10096:com.hmdm.emuilauncherrestarter/u0a74}]
