"Printer reset detected" warning, print aborted

What is the problem?

Prusa i3 MK3S+ with firmware 3.10.0 reset itself during printing. I was in another room when the printer beeped.

What did you already try to solve it?

Been reading similar reports. Found one from 2018, which blamed the bug on
Prusa firmware. The bug was supposedly fixed in version 3.4.1

Have you tried running in safe mode?


Did running in safe mode solve the problem?
