Hello. I'm pretty sure that this is not a cache issue. First I thought that this problem came up with the SCCM Hotfix KB33177653 (Azure for US Government Update) which we accidently installed on July 3rd. Accidently installed means that we do not use the US Government Cloud. We use the Public Cloud. But diving deeper into the logs it seems that this error came up after installing the latest microsoft june update KB5060842 which was installed on June 16th. So almost 3 weeks earlier then the SCCM hotfix. Even new clients which got installed with the SCCM client a few days ago still report this issue. Renaming the folder will not solve the problem.
Since June 16th, so right after installing the Microsoft June Update, I can see lots of errors at the event viewer AAD-> Operational.. there were no errors before the KB5060842 June Update..
But since i installed the update there are lots of Token Broker errors:
Error: 0xCAA5001C Token broker operation failed.

The clients work well. I am able to install software packages, the client baselines work well, i can uninstall / reinstall.. everything without any problems. But the GET_AAD_TOKEN_ERROR still persists.
Maybe this will help anyone to investigate the problem.
Best Wishes
