Bug Selection window like. color, texture etc. does not shows

Hello,

I have strange problem which I cannot find anywhere on this forum and internet. Generally in shader graph when I try to change the color, texture or anything else what can be selected, the referenced window does not appear. See screenshot below:



The window which is missing:


The only one way to open that is to open UI Debugger (ctrl+f5) and use option Pick Element. However this only works for color selection. For texture it does not works. It does not hide anywhere for information

Is there any way to fix that? This is serious problem
