tried both the cleaner didn't seem to have an afect and the newgrounds one is not able to be played on mobile
You can't say "global", that the browser version is not able to be played on mobile. But that´s a general problem on android. Android should be primary a phone os, not a high end gaming device. I think HOS has 2 problems on android systems. Memory and Speed. I read some more about ANR (Application Not respond).

There is a different between a crash and an ANR on Android, how the OS handle this. I think in your situation it looks more like a memory problem and a real crash. HOS has so much Artwork. App has some hundreds MB data. I can´t say how godot and HOS handles the memory when you start the app. But depending on the time before the game starts, there is a lot of data shuffled to a current running memory process. Also later in game, for example when you start a new game or load a game, there is a lot of coding working and memory usage again i think.
Found also this topic about reasons on android game crashings.

So it could also be a problem with newer Android OS. But my personal number one is missing memory.
There is also the possibility to connect an android device to a computer and log the crashes, but that wouldn't help you i think, it would only lead to the crash reason and could help the developers?
I "tracked" the memory usage from HOS on my Win10 System.
Starting App will use near the 300 MB on memory like the app usage on file storage space. Starting a new game or load a game will boost the memory usage to near 2 GB. I have readed at somepoint that memory usage from HOS on android system is enhanced, but we have still a lot of usage there, need to test this on android enviroment.
