Garmin Express quit unexpectedly message

In solving my problem with Garmin crashing on my Mac while I tried to sync music (the solution was to go back to V19) it seems it also deleted my golf maps. Now it's crashing while I try to update maps. I've tried going forward to V25 but it too crashes as soon as it thinks it has downloaded the base maps. This has to be the worst piece of software I have ever seen in 41 years in the IT industry. Does Garmin even have a Mac to test software on?

Does anyone have any ideas how to solve this please?
