First open cmd, then change your directory to your VirtualBox folder, the command should be
cd "C:\Program Files\Oracle\VirtualBox" if you didn't select a custom installation folder
then
VBoxManage.exe modifyvm "REPLACE WITH YOUR VM NAME" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
then
VBoxManage modifyvm "REPLACE WITH YOUR VM NAME" --cpu-profile "Intel Core i7-6700K"
It's similar to the instructions listed in the documentation, but it's the cpuidset command (https://www.virtualbox.org/manual/ch08.html#vboxmanage-modifyvm-teleport) that made it work for me. I have a Ryzen 7 2700X. Hope this saves you guys some time. I didn't see this in documentation or in issues, so sorry if this is was already written.
