My guess is this category filter confused telemetry trace parsing code :-)

For a speculative workaround, can you change those two lines to:
cat_filter =
tracing_category_filter.TracingCategoryFilter.CreateNoOverheadFilter()
cat_filter.AddIncludedCategory(TOPLEVEL_CATEGORY)

and see if it works?

     return timeline_based_measurement.Options(
-        overhead_level=timeline_based_measurement.MINIMAL_OVERHEAD_LEVEL)
+        overhead_level=cat_filter)
