Can someone tell me why my first recording works and second is freezing?

I have been having this issue all week. I wasn't having it when i recorded in 4k 30fps but now 1080p 60fps its an issue. Below is the log. Ive spent many hours trying to figure this out and reading the log is a different language to me.
I have a sony a6400 connected with a micro hdmi cable into an elgato camlink 4k.

CBR at 60000 for recording? CBR is for streaming, bad for recording and 60000 bitrate???? uh.. really
GPU is overloaded
00:24:35.646: Video stopped, number of skipped frames due to encoding lag: 16/643 (2.5%)

And follow the strong advice of the app. DO NOT record to MP4. period. remux if need be.

1) NEVER RECORD TO MP4 DIRECTLY, FOR ANY REASON. It is not a recording-safe format; if anything goes wrong during the recording, even for a split second, the ENTIRE recording will be corrupted and absolutely not recoverable by any means. Record to MKV, and remux to MP4 after the recording is complete from OBS' File menu, Remux Recordings.​
2) Record using CQP or CRF, not CBR. CBR is only used for streaming, where the back-end infrastructure requires it. CQP/CRF are quality-target based encodes, and will use as much or as little bitrate as is needed to maintain a constant image quality. No wasting bitrate on simple/slow scenes, no choking on fast-moving or complex scenes. 22 is a good starting point. 16 will result in much larger files, but near-perfect video. 12 should only be used if you plan to edit and re-encode later, and will be VERY large. Anything lower than 12 shouldn't be used unless you know exactly why you need it, and what problems it can cause.​
3) Use the Quality preset, not Max Quality. Likewise, turn off Psychovisual Tuning. Both of these options use CUDA cores, and tend to cause significant problems like encoding overload when it should otherwise not be happening.​

ignore #3 above unless still having Encoding lag issue after following #1 & 2 above. And when making a log, record for more than a few seconds, try many minutes.
 
Thank you for the reply! I believe I followed your suggestions and the problem re-occurred. Not sure why I had it at 60,000 but I will never do that again lol

Here is the log of my 5 minute recording.

Why old version of WIn10?

The general recommendation is to NOT have audio at 2 different sampling rates (though I see you are set to NOT using audio from CamLink 4K, so may not be an issue... but whether an issue or not in your specific circumstance is beyond my knowledge level

15:23:29.588: WASAPI: Device 'Analogue 1 + 2 (2- Focusrite Usb Audio)' [48000 Hz] initialized
...
15:23:29.704: [DShow Device: 'a6400'] settings updated:
15:23:29.704: video device: Cam Link 4K
...
15:23:29.719: using video device audio: no
15:23:29.719: separate audio filter
15:23:29.719: sample rate: 44100

Are you still having an issue?
Are you monitoring disk I/O?
 
I created a new profile and its on simple mode and currently works. I was afraid to even touch it after that...until now. I put it back to advanced with the recommended settings from earlier and nothing different that i can really see and it also still works.

I have free windows atm and I forget why exactly, I do remember using the paid one I had to fix my nephews PC because he messed up something reallly bad and the final solution was to reformat and reinstall windows. There really is no excuse for me to not get a key and have a proper windows. Thanks for reminding me, I've become numb to this "activate windows".

And by monitoring disk i/o that means am I checking task manager when I was trying stuff out? I did have it open but didn't notice anything abnormal, I also didn't know what to really look for.

TBH I'm pretty confused why it works now and didn't then but it does work and I am happy.
