2023.9 - tabbed-card stopped working

After update to 2023.9 my most important tabbed card stopped working. It shows the tabs in preview, but when I stop editing the tab selector disappears, meaning I can’t access other tabs than the first one.

I don’t know where to begin. Anyone see errors in my code or know about any changes in 2023.9.0 to cause this?
