I need help about deep-stream 4.0. When i try to run sample apps, facing various errors

Error list:
• ERROR: <create_multi_source_bin:714>: Failed to create element 'src_bin_muxer’
• ** ERROR: <create_multi_source_bin:777>: create_multi_source_bin failed
• ERROR: <create_pipeline:1196>: create_pipeline failed
• ** ERROR: main:635: Failed to create pipeline
• Quitting

I had tried to solve these issues that is why search on goggle and get solution like remove registry file from ./cache/gstreamer, reinstall gstreamer 1.0 but still i face the problem.

Which platform you running on, can you detect nvstreammux?
gst-inspect-1.0 nvstreammux
get more logs would be helpful,
