Client crashes when trying to save a filtered view

FragenFrager

Hello
an employee of one of our customers has the following problem: When you start with a specific Role Center and try to save a filtered view, the client crashes with the message that the server has been disconnected.
Other employees can save filtered views in the same Role Center.
I renamed the .zup file.
If another employee logs on to the computer of the said employee, it also works.
Someone an idea for a solution? Is there a limit to the number of possible user customizations? The employee has quite a lot.
