I changed application icon if user is gold user. When if the user is not gold after I changed that, don't load splash activity again. I tried create two alias actvity for these two sitatuan but I can't change icon with two alias. I tried deleted <action android:name="android.intent.action.MAIN"/> in SplashActivity but didn't solve. When I use these code without call from HomeFragment. Why have this issue now?
HomeFragmet.kt

if (clientPreferences.getIconType() != moneyCardType){
                                clientPreferences.setIsMoneyGold(moneyCardType)
                                clientPreferences.setIconType(moneyCardType)
                                val i = Intent(requireContext(), SplashActivity::class.java)
                                startActivity(i)
                            }

SplashActivity.kt

if (clientPreferences.getIconType()){
            // disable old icon
            val manager = packageManager
            manager.setComponentEnabledSetting(
                ComponentName(
                    this@SplashActivity,
                    "com.grosmagazam.ui.SplashActivity"
                ),
                PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                PackageManager.DONT_KILL_APP
            )

            // enable new icon
            manager.setComponentEnabledSetting(
                ComponentName(
                    this@SplashActivity,
                    "com.grosmagazam.ui.SplashActivityAlias"
                ),
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                PackageManager.DONT_KILL_APP
            )
        } else {
            // enable old icon
            val manager = packageManager
            manager.setComponentEnabledSetting(
                ComponentName(
                    this@SplashActivity,
                    "com.grosmagazam.ui.SplashActivity"
                ),
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                PackageManager.DONT_KILL_APP
            )
            // disable new icon
            manager.setComponentEnabledSetting(
                ComponentName(
                    this@SplashActivity,
                    "com.grosmagazam.ui.SplashActivityAlias"
                ),
                PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
