can't figure this out, new to hashcat

so I tried this, after looking through loads of guides.
I suspect my hash is in base64, and it is salted? (How do I know if I'm right?)
So that's why I used -m101
Can't really figure out what's wrong with it.
If it's to do with the fact it's salted, can someone help me figure out how to unsalt it (hahahaha… Is that even possible)



(By the way it's not a real password it's just a fun challenge so I'm fine with sharing the hash if someone asks haha)
