So i tried something from another thread with someone with a similar problem. See below.
I clicked ‘e’ and removed ‘quiet’ and edited the rd.luks… as per instructed above. Then clicked ctl +x to reboot in verbose. Please see screenshot for result
The following showed up. I tried blkid again but the result was the same. Then i plugged my usb in and it seemed it was found but not authorized for use. Trying blkid again, yielded the same result unfortunately.
Im not sure where to go from here.
P.s please expect delayed responses as im a busy lawyer and not a techie! 
Appreciate all the responses
