Hello,
the entry for def2-mTZVPP basis set of Al is not correct in the 7.5.1 release. This basis set is needed (or recommended) for usage with the r2SCAN-3c functional.
To fix this, please edit the file $TURBODIR/basen/al and remove the line
al def2-mTZVPP
that is located directly under the line 'al def2-mTZVP'.
Then, please add this block after the definition of the def2-mTZVP basis set:
al def2-mTZVPP
*
# al (14s9p1d) / [5s4p1d] {73211/6111/1}

The two basis sets def2-mTZVP and def2-mTZVPP for aluminum only differ in the exponent of the (sole) d function. It is 0.45 for def2-mTZVP and 0.3 for def2-mTZVPP.
Sorry for the inconvenience!
