.

What about booting to the other slot

fastboot set_active other

Then reboot ?

.

Alternative solution, update / reflash the system :
are you able to boot into recovery-e from bootloader ?

or
from your /IMG-e-3.3-a15-20251210556408-official-FP6 folder

fastboot flash vendor_boot vendor_boot.img

and

fastboot reboot recovery

Then, choose apply update and run

adb sideload e-3.3-a15-20251210556408-official-FP6.zip
