@maniaczek, assuming that your roms are on the SD card, you have to connect to your Recalbox thru your home network and save bios, roms and saves folders on your computer.

Do a fresh install of Recalbox and visit the wiki page https://github.com/recalbox/recalbox-os/wiki/Use-an-external-usb-storage-device-on-recalbox-(EN) (the part called Setup Recalbox to use your USB key may do the trick)

Once the usb storage has been created, copy back your bios, saves and roms only (without gamelist.xml and pictures folders)

Scrap your roms from your computer and the usb key plugged in with an external soft scrapper (Skraper for example). The old gamelist.xml are not compatible anymore and may lead to black screen at the start of your new recalbox.

Patience and calm will lead you to the resolution of your problem.
