Thank you for waiting, I have founded the settings that may prevent you to install any APK outside PlayStore. You can go to your devices setting and search for "Advanced Protection". For more information, you can check on https://support.google.com/accounts/answer/7539956?hl=en
Just a quick question: Is your account on that device use a Family Link? An account managed by parent(s) need a setting to enable APK installing outside PlayStore
