M13H or Z590 + intel 11900K + Windows 10 Pro 20H2 not friend of hyperthreading

Level 7
I built my new computer two weeks ago. Mainly for running Microsoft Flight simulator. The Bios shows a CPU SP score of 82 and a cooler performance index ranging from 166 to 180. I have a Noctua NH-D15S air cooler with two fans. I am facing the following issue:

-If I enable Hyperthreading (ABT on or off), I get several BSOD's (clock.watchdog.timeout) independently of the CPU load, light or heavy
-If I diseable HT, I get no errors after several days of use and stress testing

I am convinced that there is an issue on the Microsoft, windows side or the Intel microcode of the CPU. Am I alone to observe this behaviour ? I can live with that but it is a little bit frustratiing.

I do not make any overclock. After each Bios update, I load the default parameters (F5)

Best regards
