All of a sudden, Google made some updates this week (Week# 41, 2021), and your device may have received the error message stating "This device isn't Play Protect Certified", and which may force deleting the apps under Google Suite from your device.
Factory reset is always recommended to keep a clean system. If there are any reasons that you would like to avoid resetting your device, this is a method maybe able to help you permanently fixing the error notification and re-install ing the Google Play Store. Once this is fixed, you will not receive the pop up messages anymore, and do not hestiate updating any of the apps including Google apps.
Note:
GSF is a 16-digit RANDOM number, which may impact the success rate.
You may not get this fix in one shot, and most likely you need to be very patient to keep try.
Hint:
if you get a GSF# starting with 3 numbers, I suggest you restarting from the beginning again right from there, I would say the success rate is 20%, butfeel free to take a chance to continue following the guide. if you get a GSF# starting with 2 numbers and following with a letter, success rate is 50%, feel free to take a chance and continue following the guide. If you get a GSF# starting with 1 number and following with a letter, the success rate is over 80%, go ahead and continue.
Preparation:
1a. If you still have Google Service Assistant (谷歌服务助手) on your device, then go ahead and continue following this guide
1b. If you do NOT have Google Service Assistant (谷歌服务助手), following the instructions in below link ( or the video) until Step 16 (from thread or the body of video description), then return to this guide.

3. Uninstall ALL of your residual Google suite apps in your device (Gmail, Google Chrome, Google Maps, Google Play Games, Google Home, Google Classroom, Nest, etc...... or anything that may trigger the Google Play protect to run like Linkedin)
