My print was going well so left it unattended for a little while, came back to quite a surprise.
I still haven’t done an investigation to find out the exact reason for the failure, but the belt clamp was actually ripped off the Y-plate and then torn in half.
After looking at the part I was printing I noticed that the entire part was angled in the Y- direction, so I should’ve been able to tell that something wasn’t quite right earlier if I was paying enough attention
P.S. In case you haven’t noticed this is my own custom build, so would be surprised if people encountered the same issue with one from lulzbot
