QNN Softmax op defines pre-scale (beta) that we can fold constant scalar multiply into it.

You only need to check the QNN related build. You should have access to the build pipeline, so is the build log.
For Linux:
/mnt/vss/_work/_temp/bfb99205-f415-44a0-be47-77d7f5a6877e.sh: line 3: 118621 Segmentation fault (core dumped) ./build/Release/onnx_test_runner -e qnn -j 1 -i "backend_path|/mnt/vss/_work/_temp/qnn-v2.33.2.250410/lib/x86_64-linux-clang/libQnnCpu.so" cmake/external/onnx/onnx/backend/test/data/node
You can run onnx_test_runner to reproduce it.

For Windows:

You can run command to repro:
onnxruntime_test_all.exe --gtest_filter=QnnHTPBackendTests.ScaleSoftmaxFusionScalarInitializer
