• If you see insufficient storage when installing gapps resize the system partition on TWRP using the command resize2fs /dev/block/mmcblk0p57 then try flashing gapps

• If a gsi treble rom does not boot either the rom is not arm 32 binder 64 or your vendor implementation is broken. Try reflashing vendor from MIUI Official Fastboot Rom, links can be found here
