It's a bug in the game. There is no way that other games would not have this but then saying a fix is to wipe a pc and install a new OS.
I think we can both agree its a bug, but how and what it effects is still up for grabs.
I currently have my windows 10 build and it has the key press stutter issue.
As as test I decided to get another NVME and put a clean build of Win11 and only EA and BF6 plus drivers for my mouse and KB. I have no key press stutter on this build. Interestingly, I have more overall stutter through out the game with Win11 than I do with Win10.
I agree having to wipe you OS and start from scratch to fix this is not reasonable.
