Why is dataGridView empty?

I have a form with 4 dataGridView, in each of them I display data from my database, the data itself is displayed, but for some reason the dataGridView looks empty, that is, there is data there, and if, for example, I select the cells in the dataGridView manually or ctrl + a, then the data will be visible in the selected state, but if you do not click on the cell, it will just be white empty as if there is no data in it, why is that? How to fix it?
