BTW, this issue can be reproducible with the image in the attachment
and the following steps (at least on my local VM):

 echo 4 > /proc/sys/vm/drop_caches
 mkdir mnt mnt2
 mount foo.erofs mnt
 cp mnt/seq mnt2/
 while true; do echo 1 > /proc/sys/vm/drop_caches; sleep 1; done &
 while true; do echo 2 > /proc/sys/vm/drop_caches; sleep 1; done &
 stress -p16 -l0 mnt mnt2 -d $(pwd)/baddump   # erofs-utils/contrib/stress
