URP Global Volume not working

‘Post-processing’, which was working fine until recently, suddenly stops working. In particular ‘Global -Volume’ doesn’t work at all. After creating a new ‘scene’, even though I went through ‘Create → Volume → Global-Volume’ again, all ‘Volume’ values ​​do not work.

↓ (my current project)

It works properly when I open a new project, but why doesn’t it work in the project I created?

My project is unity 2021.3.3f1 URP.
