ABRP crashes on web when opening individual acitivity in my drives

Hi, when accessing my previous drives (German: “Meine Fahrten”) I can get as far as selecting a day from the calendar. But when selecting a specific part (driving / charging) of the day then I get the Message “Oops… Etwas ist schief gelaufen” (Oops something went wrong). Tried it for different days without success.

I used a Windows 11 PC and the Browser Firefox 136.0.1 (64bit)
I deleted website data & cookies for this site. Then newly logged in but no success.
