Un-installed OpenCPN, and re-installed it from Flat Pack :almost good for a while then immediate freezing at launch, can't even simply close it .
Desperate beta tester
Are you talking about OpenCPN 5.7.x beta?
No I wasn't, but it was 100 % my fault !
I restarted all again from a freshly formatted SD card, and when installing it, I could detect , by miracle, a loop in the file structure of my chart directory.
This loop obviously caused a crash when trying to rebuild the chart database. Please Sailoog do forgive me !
