well, after serveral tries i found an work around

as dlls of Adreno Profiler can be opened by reflector, one can use Reflexil to add patch.

my reflector cannot open QXProfilerCompatibilityCS.dll(quite weird, ilspy can) which contains malfunctioning method QXProfiler.Tokens.TokenGL3APIPushDebugGroupKHR.GetName(), so patch QXProfilerControlsCS.dll

open QXProfilerControlsCS.dll, find TraceViewES20.RedrawStateCalls, in Reflexil, add Exception Handler From

(115)callvirt System.String QXProfiler.Containers.IContainerData::LogData()


(116) call System.String System.String::Copy(System.String)


no more exception and content of api calls come back!
