3DES Is there a problem? where did I go wrong ?

Integer overflow

the numbers are too huge and hashcat detects this and prevents you from running such an insane keyspace. It needs special code to deal with such large numbers; and different data types to represent such large integer numbers, unsigned 128 bit numbers are not large enough, therefore there is the problem of integer overflow. Your keyspace for instance is about 170 bits.

then another question is how to run a brute force with a certain range of keys ?
