Galaxy s7 edge reboots trying to use most root apps

[Android Central Question]

Ive rooted my s7 edge with megisk and everytime i grant a root app permission or use big root options like for instance edit build.prop file my phone will instantly reboot Everytime... is it cause i have this Selinux is enforcing going on with my phone I also see SEandroid security too how can I get around this... I'm use to rooting my androids with superSU the chainfire method but for this particular Galaxy S7 Edge ONE CLICK ROOT uses magisk manager this time

Have Magisk restore the boot image, then uninstall the Magisk app. Restart the phone and reinstall the Magisk app. Tell it to modify the boot image. See if that works.
