An unexpected error occurred (file '', line , function '')

yesterday

After updating to the May 2025 Report Server, the error 'An unexpected error occurred (file '', line , function '')' is occurring in reports that had been deployed for a long time.

It appears that the issue might be related to date Slicers. Ig o delete the date slicer visual and redeploy, the error is gone.
