ABACUS 3.8.2 gave errors in SCF calculations that were not encountered in ABACUS 3.5.3.

Describe the bug

I use abacus3.8.2 to do SCF calculations for water molecules and the following error occurs. Changing the nbands in INPUT to be larger makes the calculation to proceed successfully, but the energy in running_scf.log is wrong. These did not occur when doing the same calculations previously using abacus 3.5.3.

Here is the warning message.

Expected behavior

ABACUS 3.8.2 completes the SCF calculations for water molecules and the energy calculations are correct, like they were before with abacus 3.5.3. Calculations using LDA, PBE can have differences in calculation time and energy results.

Doing calculations with abacus 3.5.3 also gives the following error. Why do I get this error when doing calculations with PBE?
