Can't save report

Hi everyone,

i got an issue with edit and save of existing reports.

In my app workspace i try to edit and save a report but i get the following error every time since 2 days:

I tryed with multiple reports but it's the same every time.

However i can use the Save as function after i did my changes and save as a new report, then delete the old one.

This is working fine as a workaround...

Anyone else having this issue?

Is there something i can do?

best regards,

Julian
