LatencyMon: A top-end system struggles with processing live sound?

I have a decent spec machine (see below report), but I'm getting bad audio performance. I'm using a focusrite 4i4 external audio interface, connected to a usb c 3.2 2x2 port.
Here's the report. I've made sure there's no cpu throttling in the control panel, but I'm not sure which setting to modify in Bios to disable throttling there, or how safe it is to do so. Any tips, or advice for alternative solutions based on the below latencymon report:

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

It's common for Nvidia to lead in performance. Blender could be stressing the hard drive more than other programs; I'm not sure if page faults are a sign. You might want to check the drivers page next time. Often, LAN drivers cause the most latency—do you use Ethernet or Wi-Fi? Disable any unused controller and/or update the drivers.

The statement asks for a precise list of the RAM installed.

It might be possible with 4 x 24gb units, rounded up. The math adds up to 98, but such large sizes aren't typically sold. There are still many size options available now. It seems the total RAM is listed, not the active amount. Latencymon won’t run on my PC, so I can’t verify the actual usage.

That's exactly why I inquired—it seems quite similar to mixed RAM to me.

Thanks for the updates. The issue seems to be related to no software running, and you're right about Wdf01000.sys pointing to a hardware communication problem. It might be a GPU driver concern.

resource mon shows no cpu throttling, and the spikes don't match any activity on disk, memory, or network. I considered seeing a few spikes in hard faults per second, so I adjusted my min page file to 16000 and max to 32000, but it didn't resolve the issue.

The program seems to have an issue with adding up its size—uncertain how it would reach the extra 2.088gb. It could be related to the GPU, but latency reports usually show Nvidia usage. The Windows driver framework is often mentioned in such cases. Hard page faults occur when the CPU needs data from the disk, and restricting the page file might not help since it might not be the page file. If the program accesses data not stored in RAM, it triggers a hard page fault. These aren't real problems but rather poorly named normal Windows operations. Have you considered trying the LAN driver option?

Thanks. I did try disabling wifi, lan, bluetooth, etc and uninstalled the audio interface:
