So interestingly enough demo works for me, but full version is crashing when I open level.
That's odd. Does your device has enough space? There was one user who faced similar issue for survive game.
If you have enough space, then try downloading the zip file containing android version.
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)

Android 11 RKQ1.200826.002
