Unable to run macrobenchmarks on physical devices

i tried running the ColdStartupBenchmark on a physical device - samsung a34, tests failed due to the error below, i see the same error on other projects

java.lang.IllegalStateException: Expected no stdout/stderr from cp /data/misc/perfetto-traces/trace_output.pb /storage/emulated/0/Android/media/com.example.macrobenchmark/ColdStartupBenchmark_startupPartialWithBaselineProfiles_iter000_2025-11-29-14-18-36.perfetto-trace, saw Output(stdout=, stderr=cp: /storage/emulated/0/Android/media/com.example.macrobenchmark/ColdStartupBenchmark_startupPartialWithBaselineProfiles_iter000_2025-11-29-14-18-36.perfetto-trace: Bad address

Start by reproducing ColdStartupBenchmark on the Samsung A34 or another physical device and capture the reported cp failure. Investigate the trace-copy step that reports “Bad address”; done means the benchmark runs successfully and produces the expected Perfetto trace on a physical device.
