printer stuck in "reading..." screen

[kyro1984]

Since last Monday I've encountered an unknown issue everytime I try to connect an external drive to the printer via USB interface next to the touchscreen.

No matter what I connect, USB stick or SSD drive, the screen suddenly get stuck in "reading..." for too long and the home menu suddenly pops up without reading it successfully. For years it worked just perfectly fine and now this.

Anyone knows how to fix this crap?
