Weird Light Popping with Soft Shadows Enabled

[gloomy pecan]

Here's a video of what's happening in my 6000.0.58f2 URP project. When I'm placing a building it instantiates a ghost object of the building to preview placing it, that ghost object has some lights in it. Sometimes, but not always, I get the weird light popping shown in this video clip. I noticed if I disable Soft Shadows in the URP settings asset the issue goes away. I toyed with other settings as well but that was the only one I noticed that affected the issue. Any idea why this is happening and what I can do? Thanks.

It is a NaN shader error
Most likely cause is a problem in a custom shader
But if it happens with unity's own Lit shader it can be a corruption in your project or a bug in your editor version
Camera's "stop NaNs" setting can reduce the symptoms, but would not stop the shader rendering wrong if it really has an error
