Cannot convert blob error by copy and pasting images into rich text editor

Hello,

I can copy and pasting images into rich text editor and publish, than it works fine. But if I want to pasting more images and publish again than I got the following error message:

“Server error: Contact administrator, see log for full details. undefined”

I can’t see any errors in logs (/App_data/Logs).

RTE is within nested content. When I closing and open the nested content than I get this error message:

“Cannot convert blob:https://…/… to Blob. Resource might not exist or is inaccessible.”

It only works if I go to another page and switch back to previous page. Than I can paste images without errors furthermore.

Does anyone know why?
