Consistent Premiere Pro Crashing, Many fixes attempted. Unable to hit deadlines.

Hello! I've encountered the exact same problem as you, and I've now managed to fix everything completely.

I used these two methods:

1.Format the C drive and reinstall Windows on your computer or MAC (don't waste time trying to fix other issues)
2.Undervolt the CPU to -0.1
If you follow these steps, everything should return to normal and work just like before.

Puget Systems has an interesting and data-backed page up about this. Especially comparing failure rates of all prevous gens of CPUs, noting that I think it was 11 was also a high failure rate chip by their data. Just never got the publicity this set is getting.

As they show the percentage of chip failures for each gen, it's handy reading. And it up above 10% for the 13/14 gen chips.

And you're right, cutting power to the CPU can help prevent the issue. Though they aren't sure there's any way to fix it with a chip gone loco, other than replacing it.

So your suggestion to others with those chips, to go into the BIOS and dial them down, is probably a very sound suggestion.

Correct @Christopher38865047to00  thank you for noting that here! Just heard of this yesterday. This seems to be the main issue here. I'll be contacting Intel regarding this going forward, best of luck to you! 

Hey there, I am having a nearly identical issue and I've really been at a loss over the last few months as to how to resolve it. However, I am now leaning toward the processor being the culprit, as Intel has finally publicly acknowledged degaradation occurring in 13th and 14th gen i9 processors. This would explain how the issue may have only started recently (processor was ok before but degraded over time) and why any number of troubleshooting steps (such as swapping RAM, SSD, and even motherboard, or clean installing Windows, all of which i tried) do not resolve the crashing. You can google the processor issue and read up on it, but long story short, you will need to reach out to Intel support and they will likely have you RMA your CPU. They are planning on releasing BIOS updates to partners to address the overvoltage apparently occurring, but CPUs that have experienced degradation are permanently damaged. 

I hope this helps you, I am waiting on a replacement CPU now and have my fingers crossed that I can finally finish editing some projects and get them out the door without non-stop crashing in Premiere Pro. 

@R Neil HaugenAgreed! and thank you!

I would like to add one more note here, seeing as this still could be a bug in the software. Specifically, and to reiterate, this is happening with X-AVC S files, they are read by premiere fine, they can be imported into the timeline, but it seems to be happening particularly when scrubbing through the footage. I saw a thread from 2021 on a similar issue where this codec was causing issues when using JKL shortcuts. What I'm experiencing seems like an offshoot of that issue. Scrbbing through this codec, X-AVC S 4:2:2 will either hard crash premiere or cause a BSOD on my system. Once again I'm using all up to date drivers, as well as rolled back versions for this system. Last reiteration I swear, this setup worked fine until sometime between April/June. No hardware changes made, just software updates for Nvidia Drivers, Windows Updates, Adobe CC updates. Thanks support team and engineers, hope maybe it can be recreated at some level!

i9-13900K, RTX 3090 TI, 64gb DDR5 6400mhz RAM.

Sony XAVC has been an off and on issue for some users for ... perhaps ever. Sadly, as the cameras are pretty spiffy in all.

Thanks for the update, and will be following to see what transpires.

Update @R Neil Haugen @Rach McIntire recieved a call back today and after a ton of troubleshooting it seems we've come full circle back to using a work around to transcode my filetype into a more usable HEVC/mp4 format. Something about the way Sony is processing X-AVC S is crashing HEVC codec support on my system. Why that's happening when months ago I had no issues editing this format is beyond me and apparently Adobe support. Since it's happening with Nvidia disabled on my PC I suppose the issue then has to be a Microsoft Windows or Sony issue? Leaning towards Windows but this is a whole can of worms to open now and I'll have to update this thread after I get some work done using transcoded ProRes files! Lol. Thank you both again for your attentiveness here. It's a monstrosity of an issue for me but with such a widely used camera package used in tandem with a very widely used set of Windows PC components I can't be the only one experiencing something like this. Hope this thread can develop a bit more, if Windows or Sony can give any feedback I'll update when I can!

Well that's a right nasty situation, but I'm glad you're getting some assistance from their help system. Yowza, though.
