Thanks for posting and uploading the pictures and i’m very sorry you experienced such thing.
This is a Version #1 of resin tank and they are not that durable. Normally they hold for like 1-2 liter, if you are lucky it will hold for 3 litters of printing until the silicon became white.
My suggestion is to replace it with a brand new Version #2 resin tank as it can hold for like 20 litter and is much more robust. Failure of the repaired resin tank can cause to spill of resin all over the machine and inside a sensitive components. This is not something that can be ignored while taking this risk - keep it in mind while deciding.
If the investment for new resin tank is a major thing for you, I will try to place cyano glue between the silicon to the plastic from the bottom side, and after it get dried (give it an hour even if its 3 second glue), apply silicon glue to seal for leakage. Place a nice amount of silicon to fill up to the plastic surface. If you got UV glue that will be perfect as it is much more strong and durable to forces - again, all from the bottom side only.
I will print as you suggested, as far as possible from the crack as the detach of layers from the build platform is literally lifting the silicon and can cause to failure.
Again, I recommend on replacing as spilling of resin all over the machine is not something you want to handle with, its a pain in the neck…
Keep us posted and good luck!
