Oddly enough the game is loading on my older phone. But it has it's bug such as some images don't load, PC flashes when moving and game crashed after a while. I have uploaded save files. Extract them to your Android data folder. If that doesn't work I would like to know your device model and specs.
So I tried reinstalling new akps you posted, only demo works, not even with 16bit version. But from what I see it look like installation itself fails. Because in cache it creates only 4 files + version and they have same names and bit size as demo, in comparison to save file you send.
In picture there is what demo creates in cache on the left and on the right is what full version creates.
My specs:
POCO X3 NFC
Qualcomm SM7150-AC Snapdragon 732G (2x2.3 GHz Kryo 470 Gold & 6x1.8 GHz Kryo 470 Silver)
GPU Adreno 618
6 GB ram
128 GB storage (no SSD - running dual SIM)
Android 11 RKQ1.200826.002
MIUI 12.5.2 Stable
Display IPS LCD, 120Hz (1080 x 2400 pixels, 20:9 ratio)(tested in both 120 Hz and 60 Hz)
