Resistor/Capacitor broke off, anyone knows if it matters?

So, I had some issues with installing the GPU in the case, and the GPU bottom (those metals things at the bottom) ended up scratching part of the motherboard. From what I can tell, there's a bunch of similar components all the way up, so I'd think there's redundancy, so I guess it's not that important. Here is a picture (I was told some people couldn't open postimg, both links have same image):

PC boots fine into bios, fans work, stuff are recognized, mouse and keyboard also works, but I haven't really done much beyond that.

Motherboard is: MSI B650 Gaming Plus Wifi

It's located here, and on them, it is written K72 then vertically smaller K2 (the 2 has an underline), as you can see in the above image too:

I was told to ask here, and the best guess from what I've been told is that this is this:

Paralleling power metal-oxide semiconductor field-effect transistors (MOSFETs) is a common wayto reduce conduction losses and spread power dissipation over multiple devices to limit the maximum junction temperature.

Which could mean that the others could pick up the slack.

Should I get a new motherboard?

That is a K72 MOSFET transistor, essentially an electronic switch. It's probably necessary for something but without a datasheet for the board I can only guess. The K2 underline is the date code (2023 February per the datasheet coding). And yes, it is paralleled nicely so you may be OK

Try it out for a while and see if you notice anything odd.
- Also some people guessed that this might be in the audio area, so only audio might be affected.
  
  So far, I don't see any issue (audio plays too, though I can't like tell if some frequency is missing or something, I mean, it sounds fine).
  
  What are the chances if I keep using the PC like, this could damage the other (way more expensive) parts or cause a fire?
  
  Those parts are not paralleled. They could be switches so that each rear / front I/O jack can be used as a microphone or speaker, so if youre lucky it could just be the one that lets you configure a speaker output as a microphone input
  
  You can also solder a new one on (if the old one is too ripped up). They are pretty cheap. Even with a new soldering iron it's still much cheaper than possibly a new motherboard. But i don't know whether these are at all that important, so i don't know if it's worth it.
That was an extra, I wouldn't worry about it.
