Crack in Topstone Carbon bottom bracket inner shell sleeve

Hello all, if this isn't the place for this question I could have it moved.

I have a 2019 Cannondale Topstone Carbon. Carbon fiber frame, and the bottom bracket is the BB30A-83. It uses a one piece Aluminum shell that's molded into the carbon frame where the bearings are pressed into. Apparently it's developed a crack, I've included a photo.

Any ideas on how to repair, or solutions for this? I've seen an option for a sleeve like this one from BBinfinite

I was also thinking about trying to drill a little hole at the end of the crack, then maybe epoxy and hope it stops?

Thank you all for your time and input!
