Describe the bug

When I try to install the firmware 3.14.1 on my prusa mk3s+ printer, I get the error installation failed.
The firmware installs anyway, but it doesn't allow me to select the Italian language or any other language,
if I do it brings me back to the language selection menu, you can only select the English language.
By selecting the English language the printer still works and I can print.
At the moment I have reinstalled the old firmware 3.13.2.7080 and that loads without problems.
I know that this problem is an old problem, but it continues to appear at regular intervals, some firmwares work well
like the 3.13.2.7080, while others just give an installation error.

@A11lessandro2 Good morning. How do you flash your printer?
Please use PrusaSlicer, connect via USB to your printer and follow the instructions https://help.prusa3d.com/article/how-to-update-firmware-mk3s-mk3s-mk3_2227

Often these kind of reported issues are a result that the firmware has been flashed via OctoPrint firmware updater or other ways where the xflash hasn't been updated.

There is a pull request for the OctoPrint updater OctoPrint/OctoPrint-FirmwareUpdater#325 but that has not been merged.

If you still have some issues please use a different USB cable and/or USB port.
