4-channel Fine-tuned model BSOD clock_watchdog_timeout between 45% and 80% completion when run on CPU

[NerdyKyogre]

Kind of at my wit's end with this one. Any time I attempt to split a song using the 4-channel fine-tuned model on CPU, I get a guaranteed CLOCK_WATCHDOG_TIMEOUT BSOD between 45% and 80% completion. The fast 4-channel model works perfectly, as does the 6-channel, and all models work using CUDA. If it matters, I'm using local FLACs as this is the only file type I'm interested in splitting.

What I've tried:

• Updating Stemroller (2.1.2 and 2.2.1 both affected)
• Moving the source file from my NAS to a local SSD
• Changing output type from FLAC to WAV (it seems to last slightly longer before crashing this way)
• Moving the output path to a secondary NVMe
• Reverting my overclock back to stock settings and running DISM health check + SFC
• Killing all background processes
• Using another computer entirely, with the same results
