Resolve Raspberry pi microSD corruption

I have a hardware product using Raspberry Pi 4 as its controller (it runs a python program using Qt as the graphycal interface), and despite having a soft power down button on screen, some users simply suddenly remove power from the system, causing one of three things: microSD corruption, python files to corrupt or USB stick corruption (I save some data to a USB stick). I already put the microSD in read-only mode. I need someone to solve such file/media corruptions.
