I tried reinstalling OBS, updating AMD drivers, no help. In my case, something I've noticed is that it always happens when OBS is doing a lightweight operation. I don't know if its related or not, but for example, in Overwatch, it always happens to me when I'm in the end of the game watching the results/medals (bitrate goes as low as 500 kb/s in this scene instead the bitrate set in OBS, I guess its because it doesn't need more as there is barely any movement in the game). Maybe its not important.
If it helps, this are my crashes logs:

According to both our logs, it seems like the 'faulty address' point to these files:
c:\windows\system32\driverstore\filerepository\c0309114.inf_amd64_9133a0f6cb9c56bb\atiumdva.dll
c:\windows\system32\driverstore\filerepository\c0309114.inf_amd64_9133a0f6cb9c56bb\atiumd6a.dll
Since I don't know how to interpret these log files, lets see what the OBS guys can tell about the matter.
