Update your BIOS or turn overclocks off. Early Ryzen CPUs need a BIOS update since they shipped with defective microcode.

I have check the BIOS for my motherboard and it is the latest version. Im using MSI b350 tomahawk. I dont know what else i can do. Please Help! Thanks!

EDIT: for my encoder im not using x264. Im using NVENVC H.264 which should be eating my gpu not cpu! Thanks

Do the crashes also occur with x264?

Stack trace says this is coming from libvpx.dll.

There's a few threads discussing VP9 support that may be relevant to your problem. The first, looks very similar:

I dont usually stream with x264 since my cpu cant stream at 1080p. It only started to happen twice today and it didnt happen before when using NVENC. I'll test it for a few more days to see the result.

So this has nothing to do with you setting advanced output to use encoding in VP8/VP9 (webm) via ffmpeg. This is a NVENC issue.
I'm wondering why libvpx is being invoked at all.

.webm in one of your video sources? Trace shows decoding attempt.
