Firmware seems to flash fine, Validation is failing though (3.10.1)

Hi,

i updated my firmware on my MK3S however the validation in Prusa Slicer gives me a "flashing failed" error back with the validation failed in the log.

The Printer itself shows no problems so far, so i would tend to ignore it. The printer is showing 3.10.1 in the support menu.

Maybe someone had a similar issue, I found different issues in the forum.

Here's the log from the flash:
