Question Blue screen after converting project to URP

I've converted built-in asset into URP, and now when I am in the playmode, part of the screen filled with blue color, any idea how to fix it? Few helpful points
1) It look fine in "scene view"
2) I used to convert this asset into HDRP, and had no problems
3) I found this

And as we understand it some problem with cameras, but I can't figure out myself what exactly problem is...
4) I tried to change cameras from "Base" to "Overlay" and etc. it doesn't solve the issue
THANKS!

 

It's likely that this blue comes from the camera switching to Solid Color from Skybox.

 

It's from the camera, but it's still unknown how to fix this, knowing that in built-in and HDRP it works okay.

 

Hi, you can change the camera's background color. (such as change to skybox)

 

I makes no difference, actually the problem is URP camera stacking and "priority".
