OBS crashing after reinstall (libvpx-1.dll)

[Shumittsu]

I reinstalled OBS because a browser source in the Task Manager used up a significant amount of my CPU.
Even deleting every single browser source in my scenes did not fix that problem.
I then went for a reinstall without deleting the user data.
I also uninstalled StreamElements.Live since I did not use it.

After reinstalling OBS the browser source problem is gone but OBS crashes after streaming for a few minutes.
The crash logs show me an error with libvpx-1.dll.

How do I fix this? Completely uninstalling OBS with the user data would be a lot of work so fixing this problem without doing that would be amazing.

Thanks!

Update: the OBS Discord helped me and it crashed while decoding a video. I deleted every webm/MP4 video from my sources and successfully finished a 4h stream.
Will try re-adding the files to see if that fixes it as well since this is more of a workaround than a proper solution.

Try without StreamFX. If that fixed the problem, contact the developer of this plugin about this issue.
In the crash report there's an unknown process involved in the crash.

Seems like you might be onto something. From the StreamFX Discord:

PSA: There is a known/reported bug in NVIDIA's H.264 encoder which causes it to generate corrupted/invalid bitstreams. This affects both streaming and recording, with both the built-in and StreamFX encoders. In many cases the corrupted bitstream can still be decoded with software decoders, but hardware decoders will behave unexpectedly. Unfortunately, the bug is older than I expected and predates the "known stable" driver 472.xx, so not even downgrading to the time before the new presets will change the behavior. I recommend updating to any future NVIDIA drivers ASAP, in hopes that this bug is eventually fixed.

Sadly the last few NVIDIA Drivers have been a nightmare, right now everything runs fine without using any animated webm/mp4 so I'll probably just wait it out.
