Hashcat failed to break 8 character password on NVIDA A100 - what is the reason?

[myg]

Hello!

I tried to crack a 8 character password that contains uppercase and lowercase letters, as well as a number and a * symbol with this command :

hashcat -m 0 -a 3 -O 411CD27141387751E972BF3874AA44BA -a3 ?a?a?a?a?a?a?a?a


But it could not crack and said after 2 days:

When I used exact mask then it cracked during 1 second.
Thank you for any help.
