Question / Help Studio Crashes on Launch in 32 and 64 bit - Unhandled Exception

[Confectioned]

UPDATE WITH FIX! After spending a few hours in the support chat, we resolved the issue! The problem seems to be the latest NVIDIA driver, not the GEForce Driver, but the actual NVIDIA driver. Rolling back to version 395.95 fixed the issues! Also, uninstalling Personify for the c922 Pro Stream camera fixed any additional issues on load up.

Thank you to c3r1c3-Win for taking so much time to assist me in resolving this!!

Hello,

I'm currently pulling out my hair trying to figure out this issue. Originally on the 32 bit version crashed, but now 64 does as well. I've tried uninstalling and reinstalling the program with the same issue occuring no matter what. I saw in other questions related to the unhandled exceptions it appeared to be a graphics card issue, but I've updated both of my graphics card drivers (and double check updated them to be sure before posting) and this did not resolve the issue. I've tried forcing OBS Studio to run only with the NVIDIA driver with no change to the issue. I've attempted deleting the win_mf.dll, which I saw provided as a suggestion in another thread, and this did not resolve the issue either.

EDIT to add note: I have also tried the newest 18.0.1 version with the same issues. I rolled back one version to the one I last had working to see if that would resolve but no dice.

Second Edit: Tried updating C++ Redistributable and Windows Server libraries just in case that was related, but that did not resolve it either.

Every time the error is this:
Unhandled exception: c0000005
Date/Time: 2017-03-15, 21:21:33
Fault address: 7FF8391B3FA0 ((null))
libobs version: 18.0.0

Original OBS has been causing huge issues with my up speeds making it impossible to use for streaming, and I've really been enjoying OBS Studio the 3 times I got it to run. I was supposed to stream tonight and not being able to resolve this error after trying most of the fixes I've seen has been really frustrating.

Thank you for your time and any suggestions!

PS: If the log file isn't loaded with this, I've been clicking upload and waiting for it to do so but I keep getting a a processing icon of 3 dots changing color. It hasn't changed in the past 20 minutes? I have the log file at the ready and am trying to upload it, but I can't tell if it's gone or not.

I've uploaded it to Drive just in case it is not loading:

Adding the actual log file, because I didn't realize crashes displays different information!

Tried re-running old OBS (non studio version) with all the updates and installs, but that still suffers from destroying up times and making an impossibly choppy and unwatchable stream. Re-installed OBS Studio again after cleaning NVIDIA install files to no avail. I can't stream with either version of OBS like this, and I've been loving the software :(

I'm having the same issue. I think the Windows security update on Monday broke something.

While there were a few issues, the most likely offenders where: Personify (A green screen webcam removal program), and the latest NVidia drivers.

Removing #1 and rolling back to the November 2016 release for #2 seemed to fix the issue.

As a sad update, I'm back in chat again. Everything worked fine until I restarted my machine. On restart, the drivers caused any program using them to freeze the screen and force a hard reset. Premiere Pro and OBS are both exhibiting this now sadly :(

UPDATE To add, it seems reinstalling the drivers on each restart seems to resolve it, but that's a bit cumbersome. I'm uncertain why a restart specifically is causing the crashing!

Should clarify: not crashing, but screen freeze. I can't get a log for it given this, because I have to hold my power button down to kill anything as I can't even clip into task manager.
Your fix still works perfectly for getting OBS to work, as an aside - after an install of those drivers all nvidia programs run like a dream. It's just odd I experienced the freeze hang after a restart, and I'm hoping it's not an all the time thing. But I can live with it if I must! Just wanted to update on the situation :)
