I see! Thanks for reporting this, will look into it (again...).
Thanks man, I feel your pain, and I really appreciate you looking into it (again). 😅
For the record it's really easy to create one of these blocks -- it's basically the default code in blender -- the UV's for each face are 0.25x0.25 big, so they're zoomed in a lot. -- If you scale the UVs up by 4, the effect is less jarring.
Actually, heck, it's using a free asset from the asset store, so I can just share the tile with you if it's helpful (you may need to be in incognito mode for this link to work -- or you may not need to be -- OneDrive is weird and seems to change on a weekly basis):
