Anyone know how to fix this bug?

Hi, I have the following problem.

No matter where I change my name, whether in the Steam client, on my cell phone or in the browser, my name in the Steam client is not updated. It is updated in the browser and everything works fine on the cell phone. I've already tried reinstalling Steam completely, deleting everything and reinstalling it, but that doesn't help. Maybe someone knows what to do.

Then I wish you all a very merry Christmas.
