What else can I do?

You have malware or some rootkit preventing applications from calling the GetSystemInfo function. Applications require the function to query dwNumberOfProcessors
and can only show 1 processor when prevented from querying the actual total.
@dmex thanks for your answer.
I don’t think it’s some kind of virus (but I’ll check anyway) because I reinstalled Windows about a week ago and haven’t managed to install anything like that yet.
However, you gave me an idea: could I have just overtweaked my system setup? How to check it ?
I have a bunch of settings that I store as *.reg, *.cmd and *.ps1 files and apply as needed, so maybe I accidentally used something that I didn't intend to use.
I figured out the reason.
The reason was disabled option in system boot configuration
bcdedit /set disabledynamictick yes

Old habits on new hardware
In any case, the program behaves strangely
