Core Lightning will not start after update: Cannot migrate account

StartOS 0.3.5~1 on mini PC 16GB RAM 2TB SSD

In May 2024 I installed Knots (by sideloading it). Also installed Core Lightning from Community Registry. Knots expired a couple of days ago, so had to uninstall it (because no option to change expiry in GUI) and then I installed Knots 29.2 from Community Registry. After 18 hour IBD Knots is now running OK. I then updated Core Lightning, but it will not start.

Log shows:

I wrote “Community Registry” but I guess the correct is “Start9 Registry”.
