Versions over 5.0.3 having issues accessing SD card files

Yes, I have checked and this is a new bug not previously reported.

Bug Description

Hi folks

I've decided to upgrade my version 3 of ADVi3++ to the latest. I've read through deployment instructions and flashed the latest 5.4.2 To my surprise it had issues accessing SD card. In short - it seem to be caching the content of the card accessed for the first time, and mixing it with all following attempts.

Use case 1

if a card is not plugged in, it will display an empty list when pressing Print - i.e. it would not detect the there is no card.
after plugging a card it will display only the first file from that card
to see the full list of files I need to reboot the printer (turn off and on)

Use case 2

if a card was plugged before accessing for the first time, it will display files as expected
after changing card, it will display files from the previous "session" and won't show new files
to see updated card content need to reboot.

I started downgrading until I met a first version where card reading worked correctly. The criteria for correct SD Card reader work is following:

When no card is plugged in, hitting Print would pause for a bit and write text "no card present" (not exact text, as remembered)
When a card is plugged in, accessing the card would return a correct file listing

So the highest functional version is 5.0.3 LCD version does not matter, I tried 5.4.2 LCD with 5.0.3 mainboard version and it worked (with regards to the files) On the opposite, any mainboard version above 5.0.3 would fail SD Card reader criteria.

I'm surpised that there is nobody reports on the issue, which is so obvious, so I suspected something wrong with my printer. My printer is Aldi Coocon Create Touch. It is stock config, i.e. neither equipped with BLTouch nor with filament sensor.

I updated printer with CleanEEPROM.ino.with_bootloader.mega.hex after which learned to use avrdude to flash it back. Unfortunately this exercise didn't solve anything, the issue was still there. I'm sitting on 5.0.3 and wandering what's going on.

Expected behavior

The criteria for correct SD Card reader work is following:

When no card is plugged in, hitting Print would pause for a bit and write text "no card present" (not exact text, as remembered)
When a card is plugged in, accessing the card would return a correct file listing

Actual behavior

Use case 1

if a card is not plugged in, it will display an empty list when pressing Print - i.e. it would not detect the there is no card.
after plugging a card it will display only the first file from that card
to see the full list of files I need to reboot the printer (turn off and on)
Use case 2
if a card was plugged before accessing for the first time, it will display files as expected
after changing card, it will display files from the previous "session" and won't show new files
to see updated card content need to reboot.

Steps to Reproduce

Well, it is as simple as accessing the printer w/o card and then with the card having files on it.
