Getting following error when open when rule, it is happening in one environment others are working fine. PRPC version 7.2.1 DB:Oracle

As you are saying this is happening only one of the environment, can you check the operatorID and application rule associated to him.
As the operator trying to access/ open the rule may not have access , due to the application versions / ruleset versions and ruleset pre-requisites , verify the order in both environments. Check that wether operator is having visibility to access that when rule.
is this issue still exists and as per you it is happening in one environment only - my question is here it is multinode environment ? if yes - can you try with restart the server by clearing the cache and deleting rule_marker.txt, Delete TempDirectory
