Most probably is one of the plugins. Remove them and start adding one by one until you have the crash. Then you know to whom contact.
Actually, You can see several problems trying to start a WASAPI device. Also a lot of shader filters missing, I guess from StramFX, which is having issues with latest versions of OBS. No idea if it's updated. Check on every plugin if it's updated and work correctly on latest OBS version.
So, start checking for StreamFX and Win Capture Audio. There are way too many things that can go wrong in here.
You should really consider go for a more simple scene/sources way. At least if you only have 1 computer setup.
