The version is 6.1.0. The region in the screenshot above is normal, right?

The prompt indicates a split key issue. The split process first checks whether to split, calculates the split key, then applies for a region ID from PD, and constructs new region information based on the relevant ID. You can check the detailed information in the logs of the relevant components.
