Anyone tell me exactly how this guy cracked his LCD ? what exactly happened and how .

[fromFDMtoSLA]

this could happen, if some parts stick to the FEP - loosing supports, small parts don't match to the model - . if you print the next job without checking lost parts in the tank, your screen will break, because the buildplate is pressing zu zero-level for the first layer. special to none transparent resin, you can not see this lost parts. if i start a new print, left the resin in the tank, i use a comb to check the "clean" FEP.

hope my desciption is OK.
