Recent Issue with Vulkan Games

Hello,

I have noticed since Friday (04/23/2021), any game I play that uses the Vulkan API is not working with the Game Capture source in OBS.

OBS Version: 26.1.1

Log File attached;

I tested the following games:
(1) DOOM (2016) - OpenGL (Successful game capture as can be seen in the logfile)
(2) DOOM (2016) - Vulkan API (Failed game capture as can be seen in the logfile as:

19:23:25.733: [game-capture: 'Game Capture'] attempting to hook fullscreen process: DOOMx64vk.exe
19:23:25.736: [game-capture: 'Game Capture'] using helper (compatibility hook)
19:23:25.737: [game-capture: 'Game Capture'] hook not loaded yet, retrying..
19:23:28.766: [game-capture: 'Game Capture'] attempting to hook fullscreen process: DOOMx64vk.exe
19:23:29.800: [game-capture: 'Game Capture'] capture stopped

(3) DOOM Eternal (2020) - (Uses Vulkan API by default); Failed game capture as can be seen in logfile as:
19:25:12.633: [game-capture: 'Game Capture'] attempting to hook fullscreen process: DOOMEternalx64vk.exe
19:25:12.636: [game-capture: 'Game Capture'] using helper (compatibility hook)
19:25:12.637: [game-capture: 'Game Capture'] hook not loaded yet, retrying..
19:25:31.102: [game-capture: 'Game Capture'] attempting to hook process: DOOMEternalx64vk.exe
19:26:35.700: [game-capture: 'Game Capture'] capture stopped

(4) Phasmophobia (2020?) - (Uses....not Vulkan API?); Successful game capture

Has there been an update to OBS in the past couple of days that could have caused this incompatibility again wtih Vulkan API games? Because neither of the games being mentioned here with Vulkan API support (i.e. DOOM (2016) and DOOM Eternal) were definitely not updated in the past couple of days

Might have been a GPU driver update of some sort. Or one of your applications responsible for an overlay (Steam, Discord, etc) interfering.

This is also happening with me on Rainbow Six Siege. BUT i didn't update anything. I installed R6 Analyst for R6S, and then when I opened OBS, OBS just can't hook to my Vulkan version of R6S. DirectX version works fine. The game log also looks the same (capture stopped for many times)

Welcome to the club. Here's an odd parameter to try if you can: turn on HDR in Doom Eternal. Vulkan games have refused to capture unless I turn that on.
