This error is pretty obscure. For the most part your start up messages seem ok. In particular, the kernel was able to mount the root filesystem located in the second partition of your uSD card. This to me means the basic layout of the uSD card is still ok. However, systemd seems to be getting into a target-defining file that my normally booting moOde player on an RPi3A+ doesn't. I think this is the cause of the "Failed to isolate default target" message.
I think the conservative thing to do is assume the filesystem is corrupt and flash a new one. Are you using a quality name-brand class 10 (or above) uSD card? If not, I suggest you use one. I've had good luck with brands such as SanDisk Ultra, Hitachi, and Samsung.
The conventional wisdom is to always shutdown the OS on an RPi before killing the power. For moOde this means using the m>power>shutdown "button" or invoking an appropriate script from the command line or using a real button and gpio-based solution.
Having said that, Tim has reported that he's killed power on his systems without ill effect and certainly I have too (sometimes without meaning to!). We're probably playing with fate but recent RPi models don't seem to suffer the problems experienced with the early generation models.
