ubuntu 19.04: AWUS 036ach wifi adapter not working

The device used to work and now I wasn’t able to make it work since I have 19.04 version(I upgraded from 18.04). I have another TP-LINK wifi adapter and it works so I don’t know what could be happening. I ran a command I found on this same forum and this is the output:

Do you know what could be wrong?. Thanks in advance!
