NVIDIA Optimus random hangs/freezes in Vulkan

I've been trying to migrate to Artix for the past week or so, but I cant manage to get my dGPU to cooperate. Certain applications making use of Vulkan will, after a short period of time (during which they function normally), freeze up and become unresponsive (though any audio from them continues to play). This includes vkmark (on both modes supported by my GPU) as well as at least one DXVK program run through WINE. vkcube is unaffected. Forcing the usage of my iGPU, forcing a rendering pipeline other than Vulkan, and booting in dGPU only mode all cause the problem to disappear, but none of those are an acceptable solution for me.

My CPU is an AMD Ryzen 7 4800H (iGPU: AMD Radeon Vega Series / Radeon Vega Mobile Series) and my GPU is an NVIDIA GeForce GTX 1650 Ti Mobile. I'm using the Zen kernel, but I've tried LTS and the default as well and it made no difference. I'm using the nvidia-open-dkms driver, but I've also tried nvidia-dkms as my card should support either (it's a Turing I believe?) and that didn't matter either. I've been trying to get the official method of dealing with Prime/Optimus working and haven't really tried any of the alternatives, though I suppose I'm willing to if this is absolutely impossible to get working.

I'm using X11, XFCE, and OpenRC.

I couldn't really find much that seemed very useful in /var/log, but have some random snippets from me grepping for nvidia in them:

Thank you in advance! Please let me know if I've forgotten to include something important for troubleshooting or if this is the wrong section of the forum.

Ah! I had someone else's troubleshooting thread from elsewhere (about a different problem, sadly) open and I noticed they posted some output from lsmod and lspci and it seems like it might be helpful for me to do the same:

...The distro I'm coming from (MX) had a troubleshooting tool that spit out everything useful, so I'm not used to this.
