Hello there @Gladiador2690! Let’s see what we can do here.

Another thread with the same error logs as yours suggest a hardware conflict, which would depend on your current motherboard and CPU setup. Please check the details here:

> I’ve resolved my issue. It seems to be a problem specific to certain motherboards and CPUs. I followed the steps outlined below, and everything worked smoothly afterward. Thank you to those who shared their experience with similar environments, which helped guide me to this solution. Sharing that reinstalling the OS didn’t help was a great tip. Reset your BIOS to default settings. Ai Tweaker tab: Disable MultiCore Enhancement. Enable XMP. Set SVID behavior to Typical Scenario. reference: [R…](https://www.reddit.com/r/overclocking/comments/1axepvu/optimizing_stability_for_intel_13900k_and_14900k/)

Alternatively, other cases suggest confclits with any active capture/record software in the background, like ShareX. Please test disabling any present software in your end, then test the engine once again.

Finally, to rule out video issues, please make sure to update your nVIDIA drivers, picking the “Clean Installation” option, as well as going for the “Developer” drivers, as these have more stable settings for engine work.
