DTPO- Corrupted on version upgrade, now can't open/reinstall

Hi- hoping someone can advise me. :neutral_face:

Just tried to upgrade DTPO to latest version by choosing the Install on Quit option. After quitting, DTPO would not re-open at all. I’ve had this once before, and solved it by re-downloading and re-installing DTPO. This time, however, following the re-install I get the apple ‘problem report’ window, with the following detail:
