The whole thing is way low! Good thing my rig has a ton of gain available, or I wouldn't have heard anything at all. (it didn't help either, that the player started out muted by default, and the icon to change that blends into the content) But anyway, I did eventually hear it.
Keeping my settings the same once I found what worked, and comparing different parts of the clip against each other, I think your mixing levels could use some work. The background music is a bit lower than I might have liked, and the sound effect of getting hit is way loud by comparison.
If your production volume is okay and only the post is weird, then the hit might simply be clipping. Turn it down some.

The log says you're using the Noise Suppression filter on an Input Capture, which I'm guessing is your mic, which is fine. (though I'd have it *before* the Compressor, so that it's not trying to chase the "bouncing" noise floor that the compressor produces) I've seen a fair number of people put it on everything, or on their single input from some other tool that does all the work, and then wonder what happened to their music or repetitive sound effects. The answer is that the Noise Suppressor thought they were noise because it's only designed for spoken voice, and did its best to remove that "noise".
Also, if you have the same audio source in every scene, it's probably better to make it global instead. Settings -> Audio. Even if you don't have it in *every* scene, it might still be worth making it global, and then automating its mute or fade-out/in with something like the Advanced Scene Switcher plugin:
This plugin will allow you to automate various tasks using "Macros". Macros consist of a list of conditions under which a list of actions will be performed. Examples and guides can be found in the wiki. Feel free to contribute! If you run...

It's originally an expansion of the Automatic Scene Switcher that still comes preinstalled with OBS today, but it's grown FAR beyond that! It can control pretty much anything in response to anything, inside of OBS, with whatever logic you want to have in between.
