WiFi sporadic connectivity after iOS 13.5.1 update

Since I updated my software to iOS 13.5.1, my iPhone' connectivity to WiFi is sporadic. It keeps connecting and disconnecting again and again. Even with the lightest applications like WhatsApp, the service is disrupted. Although this is not the issue with any other device I am using, hence my WiFi seems to be working fine.

I have tried all troubleshooting, restarting my phone, forgetting the network and adding again, but no help improvement.
