Because lightning 5.3 introduced a new feature

The issue here is that a large number of empty regions were found during the pre-check

Check this monitoring to confirm the number of empty regions. You can adjust the speed of region merge. After the empty regions are merged, try again!

There are too many empty regions. Check if your region merge is enabled.
