Unfortunately, turning off an RPi without shutting down the OS first often leads to SD card corruption and inadequate power to begin with probably exacerbated the issue.

My advice would be to start over and reimage your SD card. You didn't provide any Additional information about your setup as requested in the template so I'll recommend using OctoPi 0.17.0.

Red LED is the power LED, so if it is flashing it likely means something is wrong with the power supply. I see you've said you ordered a genuine power supply, but the Pi does not lie about power. When it has a lightning bolt, it means under voltage/lack of power. Maybe the supply is faulty or something?
