I am no expert, but I can point out that last year’s TT worked fine with OS 10.14 which has not been updated lately, and that most crashes this year occurred with users of OS 10.14. It is TT help desk that insists with people who signal a problem that they should upgrade to OS 10.15 (Catalina), and doing so does neither help nor creates new problems. So it looks to me that the culprit is likely to be a change in this year’s TT. In any case it would incumbent to TT to try to figure what the problems is and fix it or at least recommend a working work around.
