NDK 版本：25.1.8937393 qnn sdk版本：2.20.0.240223 HexagonSDK:5.5.0.1 8gen3

Please double check the QNN SDK version as the 'Unable to find a valid interface' error occurs when the SDK version is incompatible with the program which need to be higher than 2.14.0.

遇到同样的问题了，QNN SDK是v2.36版本，高于2.14，请问这个怎么解决的？

可能是版本太高了？回退一下版本到v2.34可能成功？ cc @oreomaker
