Hello, i've been trying to configure the audio settings for the microphone i got recently and OBS, it worked well until yesterday when the desktop audio bar started taking every single key i press and mouse click i do as sound, the microphone audio bar remains silent and i can hear the clicks in the recording.
Even with the microphone disconnected, the desktop audio record every button i press, i don't have any plugin installed in my browser playing sounds when i click like in Opera GX and it feels like the speakers of my PC have a microphone on their own or something.
I have a mechanical keyboard but the sound it does should be taken by the mic, it doesn't, it is taken by the desktop audio.

I tried .mkv and .mp4 to see if it have somethign to do with the channels but they are separated and i don't know what to do.

Usually, that problem is acoustic. The mic itself is picking that up from the air. The solution then, is also acoustic: know and use the mic's pickup pattern to reject the worst of it, put something solid in between, etc.

But you say that the mic doesn't work at all.

Are you using the "Default" device selection? It could be pulling from a different mic than what you think, because Default defers that choice to Windows, and Windoze is stoopid. If that's your problem, change all of the "Default" settings everywhere to the specific device that you know it is. Never use "Default", at all, ever.

Not Default, i use Kalley K-AN1 bluetooth headset for the audio and SF 666 Omnidirectional microphone for recording (i am just starting so my set is kinda cheap), it has a foam filter around the mic and every piece is recognized by OBS.

Here is a recording of the problem (the audio in the background at the beginning is a video of The Librarian, awesome youtuber):

That is weird! The only thing I can think of still doesn't match your description, but I'll offer it anyway. Maybe it'll spark something.

I had a rig a bunch of years ago, that used the built-in USB sound card in what was otherwise an analog sound board. Older than this one, but similar function:
I figured that USB was digital and therefore immune to the sort of "ground loop" problems that analog rigs have to deal with. But I still had a "weird warble" that changed whenever the laptop did something at all. Even just moving the mouse was enough.

Unplugging the laptop from the wall, running on battery, fixed it, and plugging it back in to charge brought it back. That's classic ground-loop behavior, but it didn't sound like the typical AC power-line hum/buzz, and it came in on a digital connection! What gives?!

Turns out that yes, it *was* an analog ground loop, that was picking up a switching power supply inside the laptop instead of the usual "shore power", which is why it sounded different. And ANY analog point in the chain makes the entire chain susceptible to picking that up. So when the built-in USB sound card converted to analog to connect to the rest of the board, the perfect-on-USB signal got the ground loop noise added to it at *that* point, inside the board.

A USB isolator fixed it. Still a ground loop, even if it didn't sound like most people are used to them sounding, so it was the same problem with the same solution: break the loop at some point, while still getting the signal across. In my case, that meant breaking a digital connection, but that's because it became analog at a different point that was practically inaccessible.

It doesn't matter where you break the loop, just as long as you do. Radio already does, so your bluetooth stuff won't cause that problem, though it might cause a different problem that sounds similar. We generally don't like bluetooth here.

Another possibility is that you have Windows set to "Listen to this device" for one of your mics, which sends it back out to the speakers/headphones, and the Desktop source dutifully picks that up. A lot of people are surprised at how late the Desktop pickup is. It's the last possible thing before the signal leaves the metal box, and even includes the speaker-specific processing in a number of cases! So it includes absolutely *everything* that that device does, with a pedantic definition of "everything".

I gotta try the USB isolator, my rig is kinda old (it still have the DVD burner at the front) and the bluetooth dongle (again, old stuff) is plugged to a multiport, it works well except for the problem mentioned.
I have another pair of wired headphones, Redragon, they work but OBS doesn't recognize them so i have to put them as Default or Desktop sound, gotta find a way to make them work and avoid the bluetooth set.
As for the mic setting as "Listen to this device", not active but i have it at 90% volume and +20db levels (i am a quiet person, working on sound louder).

I'll keep you informed if it works.
