I found another similar post (https://obsproject.com/forum/threads/obs-v29-suddenly-not-hooking-process-for-recording.163091/), but the problem here seems different.
I have tried the same setting and scene for Doom Eternal and it is hooking normally. Monitor capture is also working for DCS. I have no idea why game capture is not working.

Problem solved. Game capture is working now.
It should be caused by RTSS, as written in the official guide. (https://obsproject.com/wiki/Game-Capture-Guide)
What a joke XD
