Constant Crashing On My New PC and Wife's New PC

[NickroNancer]

Built two new computers one for myself and one for my wife, but it is crashing constantly after ten or so minutes as we talk to each other in Discord.

Running it in 4k, max settings

3070
i7 11700
16 gigs of ram
Installed on an SSD
All drivers current
All files verified
Launching from Steam for myself and from Windows for her, same issue regardless.
Let me know if I can provide more info.
