Expected Behavior
Twitch account remains connected/may be connected, adding docks and additional features.
Current Behavior
Twitch account is unable to authenticate and crashes upon attempting to sign in.
Steps to Reproduce
- Open OBS 32.0.0 beta 2
- Try to connect Twitch account in settings
- Enter username and password (2fa may be asked at first but now is not even reaching that far).
- OBS should crash
Anything else we should know?
I am using a Mac which may not be helping, and do also have a couple of plugins that do not load as a result of the adjusted parameters in this version. I do not believe this to seem likely to be unique to macOS but it is something to investigate if unnoticed in other operating systems.

Please provide the application crash log.

Here you go, sorry! https://obsproject.com/logs/nL9P4B7KHRbHfmU7

I think the conclusion on this was that this is an old/known crash that we have so far been unable to reproduce on dev machines. So we're aware that there is a rare crash condition here somewhere dating back several releases, but not sure exactly what causes it.
LooneyH commented
I was able to connect my account back to OBS by rolling back to OBS 31.1.2 so it seems that this is an issue that at least isn't present on macOS for that release.

Items 1-11 in the stacks are the same. Item 0 differs, but I'm not sure that's relevant. I expect this is the same crash. However, I'm pretty sure at the moment that this is a race condition crash that can also occur in older versions of OBS when browser panels/docks are being closed/destroyed. We'll keep investigating.
nofuture2077 commented
Have the same issue with the release version of 32 on Mac OS Tahoe 26.0
mikolashodan commented
I’m also reporting that this issue persists in version 32.0.1 on macOS 26. Could you fix it as soon as possible? It’s quite a critical problem.
mikolashodan commented
@RytoEX Hi, is there any urgent hotfix planned? This issue has been reported by several streamers on Discord every day for at least the past two weeks on MacOS, and if they are using platforms like SE.Live or similar, there is absolutely no way to bypass it manually.
Fenrirthviti commented
We are still investigating, and do not have a conclusion for why this is happening, so there is no fix to push out.
mikolashodan commented
@Fenrirthviti In my log, I can clearly see an issue: EXC_BAD_ACCESS (SIGSEGV). The crash is caused by the obs-browser module. It occurs in the QTimer destructor (a component from the Qt library responsible for timer management). The crash involves access to memory at address 0x78, which is invalid a typical sign of a use-after-free error (accessing memory after it has been freed). The crash happens in the CrBrowserMain thread within the obs-browser module. Hopefully, this information will be useful to you.
Fenrirthviti commented
Please test with PR #12716 and obsproject/obs-browser#506 applied if you are able, as we think that should fix the problem.
mikolashodan commented
@Fenrirthviti The version from PR12716 shows me without the option to connect an account. I only see the option to add a key.
Wiibleyde commented
Hello, any update on this thread ?
Wiibleyde commented
Okay, i've seen the PR, it's fixed but we just need to wait the new release, right ?
Fenrirthviti commented
Correct, we're reasonably confident we have a fix for this which will be in the next release.
