I cant render the video anymore, stuck on 0% while encoding when I try to export.

I can't figure about anything different yesterday or today except the project file. Did you export yesterday, with the same one. Try a different project, or open a new project and import in the current project, sometimes that helps.

You could also try a different export codec, like ProRes LT or even ProRes Proxy. I use those, and then make a h.264 from them, as they are visually lossless. 

.mp3's and h.264 are very bad to edit with. I always transcode mp3 to wav. Then there are no compression issues while editing. Also, I transcode or use proxy workflow when I have h.264 source, which is most of the time.

Graphics card: Radeon RX 580 series AMD 8192MB 2GHz

Processor: Ryzen 7 5700X 8 cores

RAM: 16 GB (I know is not much but I was able to work with this before with no problem)

Im trying to export to H.264, adaptative high bitrate  as aways.

it is a short video with no ultra quality at all, the media i'm using is only MP4 videos and MP3 soundtracks.

Also, at the fisrt time I open the software, the screen gets black for a while and another report bug screen pops up from AMD drivers software. It really looks like some impatibility with the drivers.

It is cool to edit the video or do whatever as usual, but i cant export.

Also my PC just restarted once while trying to export again. It was working fine yesterday, now is not 😞

There's not really much to go on there. You should post your hardware specs and media info. What are you exporting to?  What kind of media are you using, etc...
