Gravity Box has disappeared

I had 2023 SP4 and last week the gravity box ceased being visible. I was just seeing the mouse arrow. I installed 2024 SP3 and still the same problem. I tried disabling and enabling it back again, but still nothing. It is enabled because when I edit its size it seems to have the expected effect (sticking to snap points from farther away), but the square near the point of the arrow is not visible, neither in model space nor paper space. When I type a command like move/copy etc, it does appear, only while being performing this command. Any ideas how to correct this?
