Indeed, 4.19 found the corruption:

Metadata corruption detected at 0x460184, xfs_dquot block 0x4170/0x1000
User quota: bad UUID for id 55197. Would correct.

And fixed it when ran without '-n':

Metadata corruption detected at 0x460184, xfs_dquot block 0x4170/0x1000
User quota: bad UUID for id 55197. Corrected.


After that, I mounted it and ran "xfs_quota -x -c 'report /home -b'" without issues.

Thanks!
