DCS will not load and freezes when OBS is running

[Hootman9104]

Problem: With OBS running, DCS launcher freezes with black screen
DCS Version: 2.9.15.9599 MT
OBS Version: 31.0.3(64 bit)

EDIT 5/23/2025: add Windows Version

Microsoft Windows 11 Home
Version 10.0.26100 Build 26100
Windows 11, version 24H2

This may coincide with Windows update from version 23H2 to version 24H2

Steps to verify:
1. Start DCS with OBS off: 
Result: successfully launched Steam DCS twice with OBS off
2. Ran OBS "Help" menu file integrity check. 
Result: No issues found.
3. Start DCS with OBS running:
Result: DCS attempts to launch but ends up in a black screen. Let it run for a bit more, then click on it, and get Windows "Application failed to launch" and clicked to stop application.

Failed 3 of 4 times. Attached the 3 "Fail" DCS logs to compare. Seems they all freeze at the same spot, A-10 load.

One launch did succeed. 

After DCS launch, OBS can then be launched and works fine. But most of the time, if OBS is running, DCS will not load to menu.

i am assuming OBS is OBS studio. anyway i believe you need to run OBS as admin for it to properly interact.

maybe this post would shed some light.

Already running as Admin, have for a long time. Different problem than that post. My recordings are fine. Problems is launching when OBS Studio is already open. Solution is launching DCS, THEN launching OBS. OBS running seems to be affecting my DCS launcher.
