I’ve had pixel phones for at least 5 years now. I’ve probably had less than 10 random restarts, most of those would have been from apps crashing.
Sometimes the device gets slow and I restart it. But that happens maybe 3 times per year. Otherwise the phone only gets restarted when an update is installed.
You should be able to select the version of the game that you want. Right click, manage,… ??? I forgot the rest but it’s fairly obvious from what I remember. You can just pick the most stable build of 1.## from the drop down.
