CPU locked at 0.5 GHz

Hi, my newly built PC runs extremely sluggish. Both in Win11 and when booting from a linux usb the cpu clockspeed seems to be locked at roughly 0.5 GHz. Even the BIOS is quite laggy.

It's a Ryzen 7 7800X3D and the mainboard is an MSI PRO B850-S WIFI6E.

I did update the BIOS and used the clear CMOS button to reset everything to factory defaults, but the problem persists.

Any idea, what could be causing this and how to fix it?

See the attached images for screenshots from CPU-Z, MSI control center and the bios.
