I take no responsibility for any negative data lost or any other problems caused by these.
I followed these steps myself and got my own test device working, so this seems fine. I recommend trying each step at a time, don't do them all at once

Make sure to Check Date and Time Settings

Google keeps a track of your Android smartphone's date and time for the Play Store. It might cause some issues if the store does not find a time.

Step #1. Open Settings on your Android device.
Step #2. Under System, tap on Date and Time.
Step #3. Now, you should see whether your device is on the Automatic date and time provided by your network. If it isn’t already then you need to turn it on.

In case your smartphone is on automatic and your Google Play Store is still not working properly, you need to manually set the date and time. Just turn Automatic date and time off. Then, enter the date and time accurately.

Clear the Google Play Store cache

Get rid of the Google Play Store cache. It can help you resolve the issue

Step #1. Open Settings on your Android device.
Step #2. Head over to your Apps or Application manager.
Step #3. Now, depending on your device, you need to simply scroll down and tap on Clear cache or you would have to tap Storage then get rid of Clear cache.

Clean up Play Store data

Step #1. Open Settings and head over to Apps or Application manager.
Step #2. Scroll down and tap on Clear data or tap on Storage then Clear data.

Step #1. Open Settings and tap on Application manager or Apps.
Step #2. Tap on Google Play Services app.
Step #3. Tap on Clear cache button or first tap on Storage then Tap on the Clear cache. (You can also tap Manage space or Manage storage then hit Clear all data.)

Install the latest version of Google Play Services

Download and install the latest version of Google Play Services on your device. On a number of occasions, I have been able to fix this issue by simply installing the up-to-date version on my Android device.
Step #1. Open Google Play Store app on your Android device.
Step #2. Tap on the menu button (looks like three lines at the top left-hand corner of the screen).
Step #3. Tap on Settings.
Step #4. In General, you can check out when your Google Play app updates. Tap on Auto-update apps and make sure Auto-update apps over Wi-Fi is selected. Make sure your device is connected to Wi-Fi.

Reset your Google account

A number of users who had run into the same issue reported having resolved the problem by resetting their Google account. Try out this trick as well.
Step #1. Open Settings and tap on Accounts.
Step #2. Next, tap on the Google account you wish to remove.
Step #3. Tap on the menu icon (looks like three dots at the top right)
Step #4. Tap on Remove account. Make sure to do this for every Google account on your Android device.
Step #5. You will have to re-enter your Google account. Open Settings → Account and then tap Add Account. (Go ahead with the on-screen instructions to add your account.)
