"Square" artifacts in lightmap

Unity Engine

After light baking, black squares appear on objects. I thought it was a matter of resolution, but this setting does not affect these artifacts. I do not understand what the problem is. What could be causing this?

Hey which version of Unity is this? Looks like you are using GPU lightmapper. Could you check if the issue reproduces with CPU lightmapper?

Hi. Unity 2022.1.23f1, baking Device AMD Radeon RX 5700. Strange, but the issue is no longer reproduced on both lightmapper.
