First Aid could not unmount the volume for repair

My MAC Fusion drive gave me the prohibition error symbol so I started it in safe mode. Within Disk Utility I was trying to run First Aid on my Macintosh HD and it came back with "First Aid could not unmount the volume for repair. Click Done to continue>" message. I tried this on Container disk 2 and Fusion Drive itself. Any suggestions on how I can repair this hard drive?

Thanks much!

Macintosh HD - Data is corrupted I was running first aid on my Macintosh HD disk after trying and failing to run bootcamp, with bootcamp saying something like disk could not be partitioned, and this happened: Running First Aid on “Macintosh HD - Data” (disk1s2) Verifying the startup volume will cause this computer to stop responding.

From what I know, this should mean that my hard disk has been corrupted, but there doesn't seem to be any problems with the mac slowing down or anything. This happened after the Monterey update and before it I was able to set up bootcamp. Is this really corruption or is this just a bug?

volume structure error I use an app called CheckMate from MicroMat. It checks my 2019 iMac 27" hardware on a regular basis. Lately, it has shown a volume structure error. I have tried to use Disk Utility First Aid, but it fails.

Previous conversation with Apple Support suggested erasing the drive and restoring. I used disk utility to erase and restore from a Time Machine backup. The restore went fine, however, the error is still there. I tried to use TechTools Pro 13, but it doesn't support APFS format. I also used the Apple Diagnostic to check the hardware, but it found no errors. Any suggestions would be helpful.
