[RESOLVED] Failed to initialize video (on what was a previously working setup) in Windows 10

[Brattex]

Hi there,

I'm having an issue with OBS; previously OBS worked fine and I don't recall any dramatic changes I've made to my system (besides the obligatory Windows 10 updates). When I start OBS, I get a pop-up

"Failed to initialize video. Your GPU may not be supported, or your graphics driver may need to be updated."

• OBS 21.1.0 (64bit, windows)
• GeForce 940MX
• Graphics drivers updated as of a few minutes ago (to try to fix the error)
• Windows 10 (x64) Pro build 19042.746

Log file attached - anything else I should share?

I've reset the profiles under AppData\Roaming\obs-studio\basic by renaming the folder, and it still throws this error.

I have resolved this issue:

1. I initially updated GeForce drivers - didn't resolve
2. I downloaded a more recent version of OBS Studio (26.x)
   1. Upon installing it, a warning popped up:
      
      
   2. I disabled MS Teams
   3. Completed the install
3. OBS works now
4. I cannot be sure if it's MS Teams or the newer version that resolved it, but there you have it.

PS - ignore the screenshot filename, Greenshot seemed to snap up my YouTube Music page's name :-)
