Hotspot or USB tethering not functioning on Xiaomi Redmi Note 9 Pro on Android 11

My Xiaomi Redmi Note 9 Pro on Android 11 was updated to the latest MIUI. When I activate the hotspot or USB tethering, when connecting from my PC or other phones, it does not let me surf or use the internet. In my Windows 10, I enter the IP config command and everything comes out well configured, either by tethering or by hotspot, but I do not navigate in any way. Help, please.
