I dont see any dump files (.mdmp) files.
for the time in question there are multiple .LOG.1 files(from full text indexing operation), a SQLAGENT.1(shown below) and a system_health_.... extended events file.
There is also a trace file (.trc) which ended about 6 minutes before the crash and shows a normal log backup as the last entry.
SQLAGENT file:
