NO updates for Core possible, stuck on 2024.1.1

Hello there, I have problems updating my HA on RPI 4.
Since 2024.1.1 i cant update the HA core anymore.
The installation takes a backup and the blue bar keeps ons moving, the system restarts but the update isn’t installed. In the logs i cant find any problem in relation to this update.
All the other updates work fine.

Anyone else knows how to fix this?
Thx alot

Any chance you’re using the start_time custom integration ? if so have you updated to the latest… 1.17 IIRC.? In any case logs and a github issue under core might be a good start as well
