This is not any bug.
It's mean either you are using 2.8 or you are using Arm32.

How to fix ?

Just install 2.9 (64 bit) from play store lol

This is also not an bug.

You can see its loading old game (2.8).

Already mentioned before just uninstall PUBG once in loader and install again😒.

Cmon bro use some 🧠

About anticheat :

Anticheat is still not on / low.

But don't worry protection is their to avoid any kind of ban 👍.

Just play safe and avoid report.
