12:31:41.158: Video stopped, number of skipped frames due to encoding lag: 49/127 (38.6%)
You're overloading the encoder. Here's a few suggestions:
12:24:13.100: YUV mode: 601/Full
Change this to 601/Partial or 709/Partial.
Full range color increases load without a corresponding increase in quality, and for most users, will actually look worse.

Turn this feature (Psycho Active Tuning) off. There are two features in the new NVENC encoder that, unlike the operation of the old NVENC encoder, do increase load on the GPU over normal operation. This is one of them. (The other is lookahead.)
12:31:38.146: [jim-nvenc: 'recording_h264'] settings:
12:31:38.146: rate_control: CBR
12:31:38.146: bitrate: 8000
12:31:38.146: cqp: 20
For recording use CQP rate control. CBR is more appropriate to streaming (as is the bitrate you've selected).

Not related to your issue, but this version of Windows is from 2018. I would probably consider upgrading to this version:
