issues with the shader in URP

[_Aka_]

Hi

To fix the issue, use URP's material converter:
- Go to Window -> Rendering -> Render pipeline converter
- Tick Material Upgrade
- Click on Initialize And Convert

Here is the documentation about the material converter: https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@15.0/manual/features/rp-converter.html

Let me know if you still have issues.
FYI, your issue doesn't seem to happen for URP 14.0.8 and earlier.

Have a nice day
