Strange application quit behavior and VRC TestAppShouldQuit fail

[EntroPiGames]

I’m currently
finalizing the Oculus version of my application for release, but have
a few issues that I would like to resolve first.

When running the VRC
validator tests, the TestAppShouldQuit test fails, but when I follow
the steps for the manual tests
(https://developer.oculus.com/distribute/latest/concepts/vrc-pc-input-4/),
everything works as expected.

More worryingly,
when I quit my application from outside of Oculus home (ex: by
closing the application window directly from the desktop), my
application will some times still be marked as “Now Playing”
inside the Oculus app, and can’t be launched again.

Also when launching the application for the first time from the Oculus app, my application crashes on start-up with the following error:

LibOVRPlatform64_1.DLL caused an Access Violation (0xc0000005) in module LibOVRPlatform64_1.DLL at 0033:fa5b6b44.

Read from location 00000018 caused an access violation.

Restarting the Oculus application and launching again seems to "fix" the issue.

BTW, I'm using Unity v2017.4.1f1, Oculus Utilities v1.25.2, OVRPlugin v1.25.0, SDK v1.26.0.
