CannotReleaseYet

release_deposit was called too early: the current block must exceed the deposit's block plus ReleaseDelay, and safe-mode must be exited. Check the block key of the entry in Deposits against the ReleaseDelay config.

Declared by the SafeMode pallet; it classifies to the semantic code too_early.

Remediation

The required window has not opened yet; wait some blocks and retry

The same explanation is available in the terminal: btcli explain CannotReleaseYet.
