TML Crash Before Start-Up

Have figured out it's a "Failed to activate audio client!" issue.

When doing the workaround and replacing files in library I am getting a new crash. I've also attached my most recent crash log... Not sure where to go from here.

I thought it might be an issue with my audio interface, but still seeing this same crash after I've completely disabled all other audio devices except a basic pair of earbuds.

Just to be clear as well, this is new. I can play older betas, and was even playing on the current version a few days ago.

If you are getting an error such as Assertion failed: !FAILED(hr) && "Failed to find supported audio format!"Assertion failed: !FAILED(hr) && "Failed to find supported audio format!" or Assertion failed: !FAILED(hr) && "Failed to activate audio client!"Assertion failed: !FAILED(hr) && "Failed to activate audio client!" in your Natives.logNatives.log, there is an issue with your audio device (your speakers/headphones/etc.).
Things to try:

Terraria and tModLoader really don't like it if you have no audio output. If you don't have one connected, try connecting one.
If you have an audio output but you are getting the error, try switching to a different audio device (different speakers, headphones, etc.)
Make sure your audio output rate is less than or equal to 48000 Hz.
If you are using Voicemeeter, you need to configure your A1-A5 devices.
If you have Sony INZONE headphones, try setting the output device as "Chat" instead of "Game".
Try the IAudioClient workaround in the tModLoader FAQ.
