@01976 have you asked support? This seems like something the technical team may be able to look into. 402 as I’ve seen it is usually a payment error code, but may be related to permissions from what I’ve found? I know it’s not a simple fix, but I’d go to Support for sure.
This problem was generated based on the number of the records i have imported into a custom object. By deleting some records i did not need, the issue was solved.
