I have the same issue with more or less the same configuration! Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz 3.60 GHz 32,0 GB Mainboard Z390-F win10pro - it is really annoying and horrible. Also thought about re-installing, but after your comment I am not sure I will do it.
I just cite you: Someone needs to seriously look into this!
