Dear all exciting team

I want to calculate electronic properties of Sc2CO2. But the calculation does not work and gives the following error

error(genlofr): degenerate local-orbital functions
for species 1
atom 1
and local-orbital 4
ZGESV returned INFO= 3

I set input.xml, as:

<input>
<title>Sc2co2-scf</title>

Please guide me for this problem.
Thank you so much.
