RECOVERY IS NOT SEANDROID ENFORCING

KERNEL IS NOT SEANDROID ENFORCING

I had been enjoying Renovate ICE 5.2 on my S7 SM-G930F until last night. The I installed an official app called Ring - Always At Home which connects to and manages a video doorbell. After installing it I went about configuring the doorbell connectivity and so forth. I have no idea whether using this app precipitated what happened next or was just coincidental.But the phone started overheating around the same time and then restarting and restarting if I power off.I first tried restoring a backup using TWRP but saw the red text (see attached screenshot) before it seemed that the TWRP froze. So I saw no other way but to install the stock firmware again using ODIN and then TWRP again to hopefully, be able to reinstall Renovate ICE. I can't remember now the exact chronology but it wasn't easy and I ultimately succeeded. But am not yet able to reinstall the Renovate ICE.POSTSCRIPT: Well a few unsuccessful attempts I seemed to have reinstalled Renovate ICE on 5.2 for G930F. I don't remember having to doing it before but this time I had to uncheck Magisk and install with No Root. Seems this is the only thing I did different which causes the RECOVERY or KERNEL IS NOT SEANDROID ENFORCING....Stock will boot up and after I install TWRP if I format and install non verity. But if I then install Renovate ICE, I get stuck on the boot up screen seeing eitherThe only fix I can find for this is to reinstall stock ROM. Which doesn't help me reinstall Renovate ICEI didn't have this problem when I first and subsequently installed Renovate ICE but suspect something happened yesterday and maybe related to the over heating.Any advice on might have occurred or how to fix?NOTE: Even after reinstalling stock and then TWRP, TWRP still shows the red dialogue as per the screenshot, during format for example.
