Premiere Pro simply not exporting any audio whatsoever in any format

I made a ten minutes video about to get posted on YouTube. During playback, everything was alright, the preview could play the video and the sound flawlessly. Right after I finished rendering everything, I checked the video to see if everything was good, but there was just no sound. The video is still there, but just no sound.

I tried rendering some 10-20 seconds sample audio files apart, to see if my audio had problems. Still no sound

I tried rendering unedited audio files. Still no sound

I tried rendering audio files taken from the internet. No sound.

I tried rendering and replacing the audio files. No sound.

I tried nesting the audio clips and rendering them. No sound.

I tried different default rendering presets. No sounds.

I tried messing around with plenty of other settings, but still no sound.

Note that I have some voice overs recorded directly into the timeline using a Blue Microphone, but I am highly positive that this is not the problem, because any audio that I have exported didn't have audio (musics, sound effects, etc.)

At this point, if nobody knows what's going, I assume my Premiere Pro has problems (it's the trial version 2018 12.1.1 - Build 10; temporary project you can say).

Please save my soul!
