Ok, I think I see the problem. This is something you have to watch out for, even more so with Chitubox.
In this model when you hollow it out, there are actually small pockets that hollow out that are not connected to the main section, this means that they are closed sections.
The most important ones are on the bottom (see Hollow1 and Hollow3). You can solve these by putting some horizontal holes (see Hollow2).
Unfortunately there are also some very tiny pockets that you can’t really drain (because you can’t really poke a hole there). (see Hollow4). For this I would try hollowing in PrusaSlicer instead, since it will try and not hollow out these tiny spaces.
If there are _any_ closed sections that are hollowed out, those sections cannot drain and the resin that gets trapped in them will eventually cause enough pressure to bust open any print.
