DeepStream 6.1.1 error: Could not open DRM failed

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one.
Thanks

Just found you are still using JP5.0.1 which is a DP release, need upgrade to Jeptack 5.0.2 to support DeepStream 6.1.1. Please refers to OS compatibility matrix: Quickstart Guide — DeepStream 6.1.1 Release documentation (nvidia.com)
