I have error but do not know how to find where i is causedt: Error assigning cubemap texture to 2D texture property '_MainTex': Dimensions must match

Hi all! I have this error, and I do not know which texture/shader/material is casuing it. Is there a way to figure that out? I have thousands of those in my project, so I can't go one by one and guess unless I have an eternity of time, which sadly I do not. Please assist! Thank you!
