Update:
I tried but it still the same, Google play services is not installed and all gapps don't work. So I decided to download manually Google Play Services apk and install it; then with "ES file explorer" in root mode, I copied gms folder placed in /data/app into /system/app with permission "rw-, r--, r--".
Now Gapps seems to start, but I can't add a Google account yet. I read about folder /system/priv-app but I don't know if it's work.
Before manually cut folder into /system/app I tried with "systemize magisk module" but when I write su-> systemize on terminal emulator, it says "systemize: command not found"
Why? Can I solve? Maybe enable execute permission can I solve anything?
