basdamp 4.8.13 crashes directly after start, opening window on macOS 13

work with iMac running MacOS 13.4, installed (upgraded to) Basecamp 4.8.13

when starting I get to the start-window and on the moment of clicking on the screen - basecamp crashes.

I read the advice of un-installing Garmin Basecamp and files .. and the re-installing it

How will I get back my lifetime ma-updates and 10 years of routes and tracks ?

I backed  from the finder the me/ lib/app support/basecamp map to my iCloud

How do I further from here ???

thx
