Unsolved Error when taking Screenshot (grabObjectScreenshot returned null variant)

[Karl_Hund42]

Hello all!

I stumbled uppon this following error in the runner/server logs when trying to verify or take a screenshot:

SSPY:Error grabWindow: Could not grab {container=':page_1' type='TableView' unnamed='1' visible='1'}.ImageHeaderView1.HeaderViewItem4 TestVP::grabObjectScreenshot: calling grabObjectScreenshot returned null variant! Found no matching overload

Error Popup when taking Screenshot of Object

The error only occurs with objects in a certain container. Taking a screenshot of the container itself works fine.
Furthermore this only happens while operating on the target device or another windows vm but not on my development vm.

Any ideas what's going on there / how to fix it?
