When trying to capture and stream league of legends, the window capture for the initial launcher works fine, but when I try to EITHER game capture or window capture the actual game client of league of legends when I am getting into a game, I just get either the first from of the game frozen and nothing after that, or just a black screen, and sometimes even nothing at all, just transparent nothing. I have googled extensively and tried everything I can. I reinstalled obs, tried every combination of anti-cheat, compatibility mode for obs, run as admin, force capture with hotkey, turning off every overlay I can find on my computer, etc. I'm not sure what to do now, it used to capture fine and just one day it didn't and won't at all now.

It happens the same for me. I open obs and i can stream, change scenes and it works perfectly. When i open league of legends, the client (of league of legends) works weird and when i enter the game, the stream losts connection. The obs keeps working, i can change scenes but the preview window is stuck and when i try to stop the stream or close obs it just crashes and i have to close it by force with task manager. I tried streamlabs and it happened too. I have this problem since i'm using windows 11 so i don't know if that is the problem but i would like some help.

This is your problem:
21:42:08.743: Loaded scenes:
21:42:08.743: - scene 'Scene':
21:42:08.743: - source: 'Window Capture' (window_capture)
21:42:08.743: - source: 'Window Capture 2' (window_capture)
21:42:08.743: - source: 'Game Capture 2' (game_capture)
21:42:08.743: - source: 'Window Capture 3' (window_capture)
21:42:08.743: - source: 'Window Capture 4' (window_capture)
21:42:08.743: - source: 'Game Capture' (game_capture)

You're making OBS to capture 2 game-sources and 4 window-sources at the same time.
Try using only one display capture for the game itself in case non of the other methods work, like in CS:GO

I would prefer to not use display capture, and I have this issue even with 1 game capture and 1 window capture, I just made the other ones out of frustration when testing/ for other games, and most of them aren't even active.

From the analyzer:

The log contains an Auto-Config Wizard run. Results of this analysis are therefore inaccurate. Please post a link to a clean log file.
To make a clean log file, please follow these steps:

1) Restart OBS.
2) Start your stream/recording for about 30 seconds. Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc.
3) Stop your stream/recording.
4) Select Help > Log Files > Upload Current Log File. Send that link via this troubleshooting tool or whichever support chat you are using.
