Free Fire doesn't have a x86 version anymore so this is expected.
However, there are some possible ways to fix Free Fire auto close issue:
Try upgrading to Mesa 21.
Use GearLock-Package [xanmod][zen-kernel][GoogleLTS][codename:benares] Kernel 4.19.x for Android-x86 4.19.203 or newer.
Try switching Gaming protocol. Gaming protocols are a set of tools that allow Android games to run on x86-based systems.
Phoenix OS Darkmatter has a gaming protocol called Xen, which is pre-installed in the experimental build.
In Dark Matter 4.7, you need to run the extension from gearlock to change the protocols, which is a separate script from Gearlock.
There are four gaming protocols: Omega, Delta, Gamma, and Alpha. They are equal to different libhoudini versions/builds.
If you dont see the option to change gaming protocol, you can press alt+f1 or use some terminal app, then type rm /data/dminit.done and enter, then reboot. If this fails, you can go to fx file manager > system (root) / data/ and delete dminit.done, then reboot.
Gearlock allows you to apply the unity fix and choose "run gearlock extensions," arm gaming protocols, and select "delta" or some other gaming protocol.
