how to debug build failing app submission that works locally

we are trying to test submitting a test preview version of our app in preparation for future submissions, but our app crashed on launch during the automated testing phase. However, when we download the submitted test build and run it on our machines it works fine. The crash logs only gave two error messages, one of which is related to oculus use in Unity and the other informing us that we need pdb files in order to get detailed crash logs.   However, when trying to upload the build to the beta branch using ovr-platform-util I get the following error:

This build contains the following debugging files, which violates VRC.PC.Security.3
player_win_development_x64.pdb

So I'm wondering what I should do to further debug this and get the process rolling. Is there any way to get more detailed crash logs?
