Ipad (5th gen) screen spontaneous crack

My Ipad (5th gen) was sitting on the table and next thing I noticed a vertical/diagonal crack from left to right. There was no dropping or sitting on it. It has a screen protector film and always in the leather casing. Please see below (ignore the marks on the protector) .

It's 2 years old and out of warranty without any AppleCare extended warranty. There's only Apple Authorized dealer in my location and closed during this Covid 19 outbreak.

What should I do ? Has anybody have this problem? Appreciate your advise. Thanks.
