Boot Camp erased my Mac partition. Can I recover it?

I booted up my 2015 iMac in Windows using Bootcamp. I installed some Windows software. I did not receive any indication that anything was happening outside of my Windows partition. But when I rebooted in MacOS, I discovered that my main Mac partition was gone, replaced with a partition labeled "diskOs2". I believe I have most of the contents of my partition backed up, but if I could recover the partition whole, that would save me a lot of time. Is it possible to recover it?

Additional data points:

• I'm running Big Sur 11.6
• My mac won't mount the diskOS2. When I try, I get the following error message: "Could not mount "disk0s2". (com.apple.DiskManagement.disenter error -119930868.)"

Bonus question: can you help me figure out what I did wrong in Bootcamp to make this happen? All I did was update Steam, install Virtual Desktop VR, and install the Oculus desktop software. As far as I knew, I was doing this all within the Windows partition. At no point did it ask me if I wanted to erase or rename any disks.
