OK, we can see that
```
2023-11-03T19:10:25,517 DEBUG [RegionServerTracker-0 {}]
procedure2.ProcedureExecutor(1032): Stored pid=675,
state=RUNNABLE:SERVER_CRASH_START, hasLock=false; ServerCrashProcedure
021d69fb7740,44905,1699038567953, splitWal=true, meta=true
```
The target region server is already dead, as it has a SCP for it.
And in the above log, the SCP finishes before we want to persist the
location to hbase:meta in regionOpening(because
021d69fb7740,44905,1699038567953 is the one which holds hbase:meta...), and
finally lead to the NPE...
Let me think how to fix this.
