Fuji Film X-E3 will not stop locking autofocus help needed!

[aryansinghbw]

I recently bought a second-hand fuji film x-e3 and it's driving me insane. It worked perfectly for the first few days of use until all of a sudden af-l won't turn off.
Basically, whenever I try focusing in auto-mode by tapping the LCD an icon appears on the top right saying "AF off" and a green dot with "AFL" under pops up in the bottom.
even in manual mode the "AF off" text is still there.
How do I go about fixing this, I've looked at every possible resource online and can't get any help. Please get to me as soon as possible :/
