Versions of the cluster

Upstream TiDB cluster version (execute SELECT tidb_version(); in a MySQL client):

(paste TiDB cluster version here)

Upstream TiKV version (execute tikv-server --version):

(paste TiKV version here)

TiCDC version (execute cdc version):

(paste TiCDC version here)

Start in logservice/schemastore/persist_storage.go at initializeFromKVStorage and follow the stack into disk_format.go's persistSchemaSnapshot, then inspect schema_store.go's RegisterKeyspace entry point. Reproduce the startup failure with the reported GC lifetime condition if possible; done means TiCDC no longer panics during initialization and the failure has appropriate coverage or handling.
