Project Server 2019 - Reporting Database Refresh fails

Dear,

We are using Project Server 2019 on-prem (16.0.10394.20016 - November 2022).

We tried to restore Enterprise Custom Fields using Administrative Restore in Central Admin to fix an issue with one custom field. But the Reporting Database Refresh job always fails with this message:

ReportingRDBRefreshMessageFailed (24023) - RDB area: Epm, error mode: ContinueOnErrors, lock RDB on errors: False, refresh sleep time: 00:05:00. Details: id='24023'
name='ReportingRDBRefreshMessageFailed'
uid='eb66d8b7-158d-ed11-9d0d-f44f4203e4b8'
QueueMessageBody='SPValidatingBinder: blocked type Microsoft.Office.Project.Server.BusinessLayer.ReportingLayer.RefreshStorageData denied.'
Error='RDB area: Epm, error mode: ContinueOnErrors, lock RDB on errors: False, refresh sleep time: 00:05:00'

Now the reporting schema is broken with missing data and columns in tables. We tried a lot of things found on different articles, but none was mentioning this specific error or solved the issue.

Can someone help?
