Alright so here me out.
I have only tested this 2 times and will test this again multiple times to verify if my idea is true.
If you enter the blockheads and are left with a white screen, exit the app, go back in, wait until the app says app not responding, and then leave the app, DO NOT CLOSE THE APP, but just go to another app, like messages, or google, spend atleast 10 seconds within the other app and then open up the blockheads tab again using the app viewer. if it does not work then turn off ur phone for 10 seconds and turn on.
This is still an experiment that has worked on 2 occasions right next to each other.
Hopefully this will work with Android 10, as I have an android 7 at the moment.
Edit: after further testing, this does not work 100% of the time.
Im pretty sure im spouting nonsense right now but it worked a couple times. lol
It work time to time and becomes stable and does not crash if you dont close the app. Im guessing this is a ram issue with my phone specifically since I only have 1 gb
