Dear if You may not be able to change the lock screen font because the update might have reset your lock screen, and specific clock styles may have preset fonts. To fix this, go to Settings > Lock screen > Edit lock screen, tap the clock widget, and select a different clock style that allows font changes. If you want to use a custom font from the Galaxy Store, make sure it's installed correctly and that you are using the correct clock style.
