Programm Lego Mindstorms Education EV3 stürzt immer wieder ab

Hallo,

ich hoffe, die Frage ist in diesem Forum passend:
Wir haben an der Schule das Problem, dass das im Betreff genannte Programm (nicht EV3 Classroom, sondern das ältere) immer wieder abstürzt ("unerwarteter Fehler"); so oft, dass man kaum programmieren kann. Erst war es nur ein Account und/oder PC, inzwischen sind es drei.
Folgendes wird in die Log-Datei geschrieben. Ich kann damit leider nichts anfangen. Kann mir jemand helfen?

Code:
