Try, cleaning Google Play Services data in the Apps section.
After that, use the Speed Boost feature to prevent apps from loading into memory (even when not in use). Open the Security Hub, go to the settings (symbol in the top right corner of the screen), and lock all apps (enable the toggle switch). I had to lock 140 apps, but after doing that, the phone no longer loaded those apps into memory. You can leave out the ones that make sense to you.
Reboot.
