What happens if you create a new ECO Group and checkout a single part?
It sounds like the ECO Group you’re currently using might have hundreds/thousands of parts checked out to it. That would be a possible reason for the long load time.
Here some suggestion you can try
- run process Check Redundant BOMs or using SQL to verified if any repeat BOM.
- check BPM
