[BUG]: Windows 11 become extremely slow on quiet mode

Version

2.12 Beta3

OS

Windows 11 22H2 22621.1413

Device

Legion 7 16IAX7 - Type 82TD

BIOS version

Legion 7 16IAX7 - Type 82TD

What's wrong?

My Windows 11 has some really weird behaviour recently. Initially I didn't think about this is LLT issue, but after I identified how to workaround the issue, I believe it is LLT problem. My environment: Legion 7 connected to a docking station via TB4 port, all external devices are connected to the TB4 docking station, including monitors, keyboards etc.

If I unplug the TB4 cable when on Quiet mode, once plug back in, my Windows will become extremely slow, and sometimes LLT will crash. During the extremely slow period, a simple workaround is to switch to other mode, like balance or performance, the computer will immediately back to normal.

How to reproduce the bug?

1. Set power mode to "Quiet"
2. Use the computer for a while
3. Unplug TB4 cable
4. Wait a few seconds or minutes
5. Plug TB4 port back

What is the behavior that you expected?

Windows start perform extremely slow: mouse is lagging, starting a program is slow, everything is so slow
