Android Permissions & Save System

Hello everyone!
I’ve been developing a game for android. I have a full working save system, but there is a catch.
While savings works for windows, it doesn’t for my android.
So my code should be saving the game into the save game blueprint. It is all created inside game instance and also inside player blueprint for windows.

By further digging I found out that the problem may be in permissions.
I’ve set permissions in my code and in project settings, but for some reason it’s just asking for permissions to be granted, but I simply cannot grant them since “no permission requested” on my phone.
I can also disable them by unclicking ExternalFilesDir but it doesn’t make any difference.

So, if true, code goes further and saves the game. But it doesn’t work.
I’ve been searching forums and if I am correct it’s all about permissions. But I may be wrong.
My project settings:

So, actually, despite this permissions, how I can get a working save system on adroid 33?
