The Problem:
Manipulating the thumbsticks on my Xbox One controller (connected via cable or wireless) causes huge latency spikes and audio stutter. The problem gets worse over time, until eventually my PC begins freezing anytime I move one of the thumbsticks. Pressing any combination of buttons on the controller does not cause latency spikes, it only occurs when moving the thumbsticks. I can switch instantly to keyboard + mouse and the latency spikes no longer occur. My normal latency peaks at around 300, but when using the thumbsticks it is jumping up to 4000 and higher, which is when they begin to freeze up my PC.
Setup:
Windows 10 64 bit, i5 6600k, rtx 3080ti, Asus Z170-A Motherboard.
I have updated drivers relating to the Xbox game controller, including using the Xbox Accessories app. My BIOS is up to date and I have turned off all power saving options. I heard of problems with Realtek audio drivers so I replaced them with Microsoft's drivers but there was no change. I also tried with antivirus and google chrome shut down but it didn't change anything. And I have tried different USB ports, including the ones my mouse + keyboard use.
On a fresh restart, I can use the Xbox controller for about 3-4 minutes before latency spikes begin showing in LatencyMon. They gradually get bigger and after about 20 minutes of use, moving a thumbstick causes so much latency that it freezes my PC. It goes back to normal instantly if I no longer touch the thumbsticks. I really don't understand why it's only the thumbsticks that are causing such huge latency spikes. Unfortunately I don't have another device to test the controller to rule it out, though I would be very surprised if a controller fault could cause this issue.
Any help is appreciated, thanks.
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 problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:02:11 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 3522.40
Average measured interrupt to process latency (µs): 7.391501
Highest measured interrupt to DPC latency (µs): 3393.0
Average measured interrupt to DPC latency (µs): 2.783829

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
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.
Process with highest pagefault count: avastui.exe
Total number of hard pagefaults 269
Hard pagefault count of hardest hit process: 95
Number of processes hit: 19
