***Alright this is a pretty easy fix***!
Here a few things you can try. I have a feeling that the launcher your phone uses either may not be setup correctly in settings or is corrupt. Don’t worry tho here are a few tricks!
* In the most recent App you’ve managed to enter ''go to the top of the phone and swipe down''. This should bring up the control centre which has brightness controls etc. You should also see a settings toggle in the control centre. You may need to just swipe left to go on to the next page of the control centre to find the setting toggle. Once clicked, in your settings app you want to search for ‘launcher’ - This should bring up default apps, click on it; Launcher; And set the MotoLauncher as default. It should look something like This:

* If this doesn’t work, don’t worry! Do the same process but click on apps; Playstore and click ‘open’. You will want to install something called ‘Nova Launcher’. Once installed, you should be able to open it. It should look something along the lines of your old launcher. Then, it should ask to be set as the default launcher and click ‘Yes’.
Hope these methords work. If not you will need todo a hard reset which can be found on hardreset.info
