Google Search opened via widget won't stay open in the background

I use the Nova launcher for my Samsung Galaxy S23 Ultra. I have a Nova widget of the Google search bar on my home screen I like to use to quickly search things. I use the Nova one instead of the Google one because the Nova one changes its appearance to fit my phone's theme.

My issue is that recently, (probably from the latest Android/OneUI update) when I open Google search from this Nova widget it closes as soon as I minimise it to the background. Opening Google via any other means is fine, it's just opening from the widget where it breaks.

I found this post about the same issue but a different widget app and not Nova launcher specifically, so that leads me to believe it's an Android issue itself.

Does anyone have any solutions to fix this issue?
