All indicators light up very urgent help.

My car gave the error that I uploaded the video to youtube for the first time after 5 years

The battery did not get better without removing and reconnecting the terminal, what is the cause of the problem? There are those who say, but my vehicle's manual transmission and transmission were revised in 2021 and their maintenance was done. The vehicle's 10,000 maintenance was just done. The vehicle had a misfire in the 2nd gear recently, the spark plugs were changed and an injector was cleaned, then the ignition coil connector was checked, the room was made, then the ignition coil was checked in the vehicle intermittently, the engine fault lamp is blinking at intervals of 4 5 seconds, and today first time doing this

I wonder if I'm alive
