OBS won't work after 5-6 recordings

[Flyfisherman]

If I play a game in full-screen mode and have OBS in the background ready for recording, it works fine for about 5-6 recordings, then it will not work any more no matter what I do.
In that case I have to restart OBS to have it to work again, but only a couple of times then it is impossible to activate recording (via hotkeys) again.
It happens in all games.
This is frustrating, since I can't trust that a recording has been made, fortunately I have a dual monitor setup with an Explorer window open of the recording folder on my other secondary monitor so I can actually see when a recording starts and ends.

* When this problem occurs, OBS cant be stopped the normal way, one has to terminade the OBS process from Windows task manager.
It seems to me that OBS has somewhat crashed.

And btw. OBS recordings is on another SATA disc and not on my Samsung 980 Pro 2TB M2 SSD.
Actual logfile could not be opened, so my attached logfile is the latest from when the recording actually did work.

Use something other than the AMD encoder, or downgrade your drivers.

Ok. I changed from GPU h/w to s/w encoder and it seems to work.
The downfall is while recording that the CPU has to work harder and gets a little warmer (64 degr C. approx) and the cores utilization increased to approx 65% (less for some cores) in total with current game. The good thing is that it is a 16-core CPU.

Btw. Downgrade the driver is not an option; one is that there are bug-fixes that addressed some important issues for my GPU, another thing is that this problem is an old one that has been for a very long time, even with older drivers before.

Any idea why AMD h/w encoder doesn't work? Or is it because the GPU hardware is occupied with the game engines graphics?
