I found delete /data/misc folder can solve this problem
In recovery:
adb root
adb shell
mount /dev/block/by-name/userdata /data
ls /data # check if you mount success
ls /data/misc # delete this folder
rm -r /data/misc
umount /data
exit

This is correct. I can confirm this issue still exists a year later.
