Good luck - hopefully some more knowledgeable on the Behringer X32 mixer will chime in. You may want to update the Post Title referencing that mixer
As for me.. Same here in terms of House of Worship and getting mixer to OBS. In my case it is a Presonus AR12 USB.
Side notes
- default enabling of Win10 Game DVR should probably be turned off
- Why change to OBS Video default and using 'Area" rescale filter? I've never seen that before. Bicubic being the default, and Bilinear being better at cost of CPU. Ther are other options/trade-offs, and this is from memory, so you are forewarned to check/confirm separately
- Facebook (if that is your target) has recently allowed broader 1080p streaming (don't have to join Gamer special program to enable). so if you have the PC capable of 1080p, and upload bandwidth (I use 7+Mbps, though you could get away with less) you may want to consider upgrading??
Sorry not a direct answer, but things that may apply
- What exactly does Window OS see? each channel, or just a mono or stereo Main mix? Or all of the channels? And how many channels are you using?
I ask as, when I started, I found the OBS Default Global Audio sources, especially Desktop Audio, to cause me grief (I was new to OBS), so I disabled all of them. And then added a New Audio Input source for the microphone and was all set. Currently, I have a sub-mix analog out from the mixer into a gain adapter to a 3.5mm TRRS cable into PC (and front panel port works well to motherboard based Realtek chip, while rear panel doesn't.. go figure). I grab a sub-mix as Main mix is for in-person amplified speakers, so we have some additional mics for piano and pipe organ/choir not required for in-person attendees. What I'd like is to either use a DAW or OBS to control individual mics (I have a pipe organ mic at back of Sanctuary causing a noticeable echo when audience quiet and single speaker talking). The challenge is DAWs often won't output to Windows Audio sub-system. Presonus's Studio One Pro v5 with Listen Bus will output to Windows, but the included 'Artist' license does not. At which point, virtual loopback solutions, or something like Reaper's Reastream VST plugin are alternate methods to get Audio to Windows OS. Sorry, I don't know specific to Behringer
What often gets mentioned is using ASIO drivers, or the native mixer drivers, to get individual channels to Windows OS. But others have commented on struggle with audio channel re-enumeration with ASIO. If you are hoping for a simple Mono or Stereo signal over the USB, then that would be a mixed output, so recognize the likely desire to have a separate mix for in-person vs livestream
Clearly your log shows an error regarding initializing the audio input
14:01:29.171: WASAPI: Device 'Microphone (2- X-USB)' [48000 Hz] initialized

Hopefully someone will comment on this, and the PC setup for Behringer X32 specifically
in case any of these help (probably not, but just in case) -

Then, a possible next step [after you fix what you asked about) for Windows (not a MacOS user so not sure if native capability there) The CoreAudio AAC encoder would possibly be an audio encoding quality improvement over the built-in OBS AAC encoder. If you'd like to install CA, it's quite easy. Here's a guide:
