Slow SN750 4K Random Read/Write

Hi there,
I am getting really slow performance in 4K Random Read and Write benchmarking.

I decided to reboot my computer in safe mode and the performance was nearly double. I thought it might be caused by BitDefender (antivirus). So I uninstalled that and restarted the computer to get the same low performance.

Here is my motherboard for reference:
ASRock Z390 Phantom Gaming 4 (Most recent Bios 4.4)

Also I am running a second SN750 1TB drive that gets virtually the same low performance.
Lastly, I am also running an m.2 Intel Wifi 6 AX200

So all three of my M.2 slots are filled. I currently have no SATA drives connected at all. Any help would be much appreciated. Thanks!

Just an update. I completely re-installed windows just in case there was an issue. I still have the exact same problem. I thought I might install some of the drivers that came with the motherboard, but none of them were specific to NVME. I tried them anyway, and it didn’t fix the problem. I’m surprised that nobody else has this issue?!?!
