Mouse cursor disappears after enabling Secure Boot (ASRock Z390 Phantom Gaming 4-IB)

Hey everyone, I’m having an issue with my PC.

When I enable Secure Boot in my BIOS (ASRock Z390 Phantom Gaming 4-IB, Windows 10 Home), my mouse cursor disappears as soon as I boot into Windows. The mouse still works in BIOS and before Windows loads, but once I’m on the login screen or desktop, there’s no visible cursor.

If I disable Secure Boot, the cursor comes back normally.

I’ve already checked:

• Device Manager (shows HID-compliant devices)
• Tried different USB ports
• Mouse works fine on other PCs

Any idea what could be causing this or how to fix it?
