    Workaround:

    The problem resides in the LightingUtility.hlsl file, at light 68.

    In order to fix it you have to:
    1. Duplicate the URP package folder found in PackageCache
    2. Move it to packages folder
    4. Uninstall URP from the Packages Manager
    5. Edit [URP Folder]/Shaders/2D/Include/LightingUtility.hlsl, and replace this line (line 68):

    output.shadowUV = ComputeNormalizedDeviceCoordinates(output.positionCS.xyz);

    with

    output.shadowUV = ComputeNormalizedDeviceCoordinates(output.positionCS.xyz / output.positionCS.w);
