Read first page and have 4 sets of wheels running tubeless. Pretty sure the sealant won’t hold the tree on the rim and I need to deflated the tyre to get the core inserted as the shot blaster will not work with the core in. Tyre stays up nicely if I don’t take the blaster off. Will try extra rim tape.
Try leaving the tyre inflated for a bit with the blaster on? Could reshape the tyre a bit, like fitting an inner tube first and leaving it overnight(did you try that?)
Otherwise could get a third pair of hands and just jam the core back in before you lose too much pressure.
