We’re trying to hunt down why packaging is intermittently failing. On one system it always fails, on another it 's random.
The build portion completes successfully, the log identifies there are zero errors, a few warnings, then critically fails with the below EXCEPTION_ACCESS_VIOLATION.
We’ve looked at the FWasapiStreamManager class from the call stack but we’re not directly using it.

Despite the warnings not being an issue when the project does package we are currently re-writing the offending UltraLeap plugin to address the majority of them anyway.
The remaining 9 warnings are all long package name generation warnings despite the project sitting only 27 characters from the drives root.
LogCook: Warning: Unable to generate long package name, /Interchange/Pipelines/DefaultGLTFSceneAssetsPipeline. Input '/Interchange/Pipelines/DefaultGLTFSceneAssetsPipeline' is not a child of an existing mount point.
We’ve deleted the Intermediate, Saved, and DDC folders, run map checks, and verified dependencies multiple times.
What else are we missing or should we be doing?
