German here, can confirm. "Fehler" or "Problem" are used very commonly. Some demographic is using "bug" but the classical industry (e.g. automotive, manufacturing etc) still uses German terms. There's a "famous" course at the KIT in Karlsruhe where the professor only uses German terms for everything related to Computer Science to make a point about most stuff originating by German researchers when it comes to basic concepts in CS. So the professor is using terms like "Stapel" instead of stack, or "Rechner" instead of CPU etc.
