I am sorry but I have no further solutions or ideas to suggest you on this matter.
You might want to get it checked in a shop or authorized repair center to see if there's a hardware problem.
Someone with more expertise might be able to help.

Hey there, recently I've got a problem that causes only one core to work 100% always and causes my laptop to be slow and sluggish (i did a clean install of Windows 11)
I tried in Linux and the problem persists there too, but the workaround in Linux was unloading the "intel_lpss_pci" kernel module by this command -> rmmod intel_lpss_pci (or blacklisting it in Grub)
in windows, i couldn't find any equivalent for it and i don't know how to find it and disable it
in task manager, it hides behind system interrupt (just like Linux, but in Linux i could trace better, in windows, i guess i don't have that much level of freedom?)
here's whattask manager and CPU cores utilization shows
