@maioni Your problem is not Recalbox: you face this problem by copying files via an adapter in Windows 10. Your problem is not Windows 10: on the 32GB SD card there is no such problem. No other users have reported this type of problem, so it's not a bug. Everything indicates that the problem is your SD card, although you say that "there is no problem it is not original and it is not class 10", this type of problem is totally related: in your original 32GB SD card and class 10, you don't face any problem. The correct thing is to change your SD card for an original and class 10. If despite knowing that the problem must be with the SD card, if you still want to insist, what can I recommend: Format the SD card and reinstall the system.
