Try to eliminate decoding errors by disabling hardware acceleration (make unchecked the "Use hardware decoding when available" or "在可用时使用硬件解码") for your media sources. This will make log-file more readable.
Code:

OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.

(game and display capture sources in the same scene, HAGS - all may lead to bad OBS experience)

So I uninstalled obs and reinstalled it and reset all settings of obs
But the problem is still not solved. Although it prompts that hardware acceleration is turned on by default in win11, I don't think it is a problem with this thing. This function was always turned on before the problem occurred.
In addition, because I reset all obs settings, the current obs only added monitor capture, which still did not solve the problem.
I solved all the problems according to the analysis tool, but when the game is opened in full screen, the OBS output screen is still still and frozen.
It’s still the same as the video I took before (the additional monitor is plugged in for intuitive performance, because you only have one monitor and you can’t see what the obs status is when playing in full screen)
After that, I tried to change the direct connection function of the laptop to the mixed output mode, and the obs problem magically disappeared. However, the problem still existed when I switched back to the direct connection function.
I have tried updating the graphics card driver, but the core graphics driver still cannot solve the problem.
One problem with using game capture directly is that after selecting the full-screen window, the position of the game displayed on obs cannot be adjusted. This is the main reason why I insist on using monitor capture.
Capture of the game that is running on integrated GPU is different from the capturing of the game that is running on dedicated GPU. Usually Windows renders its desktop (all you see after PC powered on) on integrated GPU. Graphics heavy games usually rendered by dedicated GPU. "Game Capture" source of OBS uses special technique of capturing - it copies textures (final picture of the game) before they appears on the screen. To copy texture OBS needs to be run on the same GPU. Applications running in fullscreen (not borderless window but true fullscreen) can take full control over the display device - this picture "never" blends into general picture of desktop, let's say Windows can't draw above it, or below it, or left to it, or right to it. Thus, OBS has different sources to capture applications - the "Game Capture" and "Display Capture" (not for fun but for capture to work properly).
Depending on your Windows version and what sources you wish to use, you may need to set OBS to run on a specific GPU. Not sure which Windows version you have? Press Windows+R and run "winver". For Windows 10 1909 or newer: Open Settings and search for "Graphics Settings". Select "Classic App"...
