I've tried many different things to solve my problem, and I've made progress.
1. frame drops
-> Use 9on12 option
2. EXCEPTION_ACCESS_VIOLATION
My computer could not select 44100hz, so I had 2 options.
1) Connect usb DAC and select 44100hz
2) FlexASIO
Both work fine, but I used ASIO for a more consistent experience.
The answer from @bicarus was helpful. Many thanks.
The frame drop is resolved, and the resource utilization is in the expected range. However, there is still a problem.
When I select a song to play the game, it plays at a very high speed.

We will be spending some time working on this issue.
Incidentally, I asked the question because I want to solve the problem, not to be ridiculed.
