Hi @Acarlosr thanks for the report. Do you mind confirming what arguments you passed to arc-node-execution in these 2 attempts? Since it's a pruned snapshot, you will need to pass --full or another pruning configuration to the client otherwise a consistency check will trigger which will try to unwind to an earlier height.
