Help me analyze Crash Reports

[InfantryInk]

Hi everyone

First I just want to say I been on here for years ad this place has always helped me. This is my first time posting so I will try to be as clear as possible with my issues. My OBS has been randomly crashing a lot more lately and I've finally hit my breaking point. First I thought it was outdated or incompatible plugins which may still be the case but I can't tell anymore. I feel like its different everytime.

As of right now I just got windows 11 and OBS is crashing a lot more. Can someone help me analyze this crash report and tell me exactly what this instance was?


There is gonna be more crashes when I switch my scene collection and I will post them when it happens. Thank you to all those that help.

Yes it would be a plugin, you'd need to remove them until you figure out which.

Isnt there a way to tell which one is causing issues? Or is it better to do it one at a time?

Only hard part is idk how to trigger the issue to test it. Its very random

Can you attach regular log file from this session?

If you look into a crash log with a text editor, for example Windows notepad, you see a list of app threads present at the time of the crash. The top thread is the one that crashed, and at the right side you see a list of dll files that executed that thread. Usually, this is the place where you would see a plugin dll if a plugin crashed. However, in your log there's no plugin dll visible, so it's more difficult to troubleshoot. It may be a plugin corrupted some internal data structure so it crashed later somewhere else.

In your case, it seems OBS crashed while deleting a source. Do you have plugins that create their own source types? Or otherwise deal with addition/removal of sources? Add custom menus, custom UI? These would be the ones first to check, update or remove.

In the bottom of the crash log you see a list of all dlls involved in OBS, including all plugin dlls. I see you have the streamelements plugin installed. In the past that was a common source of all kinds of crashes, so I recommend you uninstall that first and see how OBS behaves.

OK. Details.

However, in your log there's no plugin dll visible...

It was already unloaded on application close. Application was about to close when dll function called (the thread next to the crashed program thread, see below, has info about closing OBS). But OBS running many threads, so it was not easy to close all properly...

Main error. This number has special meaning. In case of the "c0000005" it means that there was attempt to access the RAM that is already marked as "free" or occupied by other structures/processes/users etc:

Unhandled exception: c0000005
...

Next lines should be read from bottom to top. The top one is the latest command that is failed. Here it named "<unknown>" and it was at address "0x7ffc86c1f2b0" (some function call, nothing at this address anymore, so it is name "unknown"):

You may not look at the rest of the lines, but the:

...

From previous reports I know that this plugin uses few other linked libraries, thus thing becomes complicated... Because this plugin lies out of OBS plugins dir - it usually comes out of scope when user looks for faulty plugins.

The "StreamDeckPlugin.dll" plugin a lot relayed on signals, so I would start form it.
