According to the output you provided previously, OSD.51/90 might have
unfound object. To shuffle object again, you could do:
# ceph osd set noout; ceph osd set nodown
# systemctl restart ceph-osd@51
* wait for OSD.51's process to be up
# systemctl restart ceph-osd@90
* wait for OSD.90's process to be up
# ceph osd unset noout; ceph osd unset nodown
If your cluster is big enough, please do this very slowly.

Or you could also do to trigger scrubbing pg:
# ceph pg scrub ${pg_id}
