Windows 10 – CPU frequency at 0,4 Ghz and 100% CPU usage

I have following problem.
Sometimes the CPU in my laptop has frequency changed to 0,4Ghz and CPU usage is at 100%.
This can take few minutes and it takes at least 20-30 seconds to wake up laptop from this state.
I attached Intel XTU screenshot with this behaviour.
I’m using Best Performance power profile and charger. (it’s not on the battery)

My laptop is Lenovo Carbon X1, CPU i7-7500U. Windows 10 10.0.19041.
Everything is updated. (system, drivers etc.)

What can I do more ?
