There are many causes of sleep failure. In the 260430 system, we fixed the RDS hibernation failure issue, meaning that if you were listening to the radio before shutting down, the next startup would most likely restart.
There are many other causes of this phenomenon: after sleep it still runs a high-frequency app, and the total current exceeds 1.16V (the voltage conversion current at pin 13 of the MCU can be measured).
Apps running in the background that have actions that prevent hibernation or crashes can also cause this issue.
Shutdown after sleep exceeding 70 hours (MCU firmware default)
After a certain number of successful sleep cycles, it will be forcibly restarted once (system count).
There are many policy discussions about dormancy
I have an MCU version here, please try it. If it solves the sleep issue, this version removes current detection during sleep (MCU pin 13 voltage).
