SSRS - Microsoft.ReportingServices.Diagnostics.Utilities

I am troubleshooting an error in SSRS we want to alter a subscription and set it to the next 5 min from now, but when it gets there it does not run. other than that, I see these error messages in the reporting services execution logs : > 0-27!4270!07/01/2024-12:54:47:: e ERROR: Throwing > Microsoft.ReportingServices.Diagnostics.Utilities.NotEnabledException: > , > Microsoft.ReportingServices.Diagnostics.Utilities.NotEnabledException: > The requested functionality is not currently enabled.; question: How to enable these diagnostics utilities?
