macos first aid volume could not be unmounted

I also tried resetting PRAM/NVRAM and the SMC per AppleCare's advice, but I doubt this has anything to do with my APFS volumes.

I have tried running Disk First Aid multiple times from Recovery and Internet Recovery, booted into Single User Mode and tried to run fsck_apfs -y from there, all to no avail. This is on the new 'Data' volume that Catalina creates for your files, aside from the read only system volume. Performing fsckapfs -n -l -x /dev/rdisk1s1. Restoring the original state found as mounted.
