Encoder error crashing obs/stream but GPU is not overloading

[Bored_Banana]

Having a strange problem this week where my stream will completely stop and OBS will sometimes crash (the OBS crash doesn't happen everytime the stream is cancelled). I've uploaded relevant logs to the analyzer and the most notible things to me are "#% GPU Encoder Overload" and "Encoder start error".

I just ran a benchmark stream + recording session that lasted 5-10minutes before crashing, here's the link to the log's analyzer
Also attached is the OBS crash report, and an AMD hardware log, showing the highest usage my GPU reaches is 80-85% but that was 5 minutes before the OBS crash. CPU does reach 100% but that seems to be ~15s after the crash so I'm not convinced its causing the crashing.
For some hardware context, I upgraded my GPU from a 1070 to a 9070xt in Novemeber, and haven't noticed any sort of encoder or OBS issues until now. I never had any problem like this with the 1070, and do not believe I have increased the graphics settings too much in the games I stream since upgrading, so I don't know how it could be a GPU load issue unless there is something I'm missing.

I have noticed in all the logs where the stream crashes (with or without OBS crashing), the following lines are present towards the end of the file;

[texture-amf-h264: 'advanced_video_stream'] amf_encode_tex: SubmitInput timed out: AMF_INPUT_FULL
Error encoding with encoder 'advanced_video_stream'
[rtmp stream: 'adv_stream'] Encoder error, disconnecting

This makes me think its something to do with the encoder I have selected, but my only options in OBS for streaming are AMD HW H.264 (AVC) and x264. My understanding is x264 is a CPU bound encoder which I am trying to avoid, so I'm not sure what to do, espeically because I'm not even sure if thats the actual issue. I have added screenshots of my streaming and recording settings, wasn't sure how else to share them here.

Any suggestions or ideas would be greatly appreciated thanks
