I tried looking at the dependency tree but couldn't identify any discrepancy in versions. In general, NoClassDefFoundError occurs when a class is missing as well as static initializers fails. From the error, I feel that's the latter in this case. Is it possible to set a breakpoint at com.google.cloud.bigquery.storage.v1beta1.Storage line 5216 and see any failure in static fields of the Storage class?
