Trying to add/run a subscription to a existing SSRS 2019 report I'm getting the error below in the SSRS log file where the ONLY thing I changed was my actual login to Domain\username.

however.....nothing that I found here https://learn.microsoft.com/en-us/troubleshoot/sql/reporting-services/call-authzinitializecontextfromsid-api-fails makes sense as:
My AD domain login is system administrator+system user at site settings AND is sysadmin in SQL Server running the ReportServer database AND local admin where both SQL 2019 and SSRS 2019 are installed on a Windows 2022 Standard Server ;
Has all Content Manager, Browser, Publisher, etc...at the report folder level;
The SSRS is running under a Domain\login account as noted at Method 2 above link.
What else is needed in SSRS 2019 aside ALL the above for a administrator to be able to create/run a successful Subscription?
