The issue

Found this crash in crashlytics, our QA was able repro accidentally once and said it happened on app startup.

This looks like the same issue as #1968, but the solution was updating to 3.0.8 and we are already on 3.2.5, so don't think its version related. The interesting thing is the comment made in that ticket at the end saying to remove AVPro assets before importing, could this be the actual cause of the crash?

We're not sure about this one.
Are you able to update to the latest version and retest?
Are you able to send us a minimal project that can reproduce the issue please? to unitysupport@renderheads.com

[SamJenkinsAim]

We will update to latest version and see if we can repro. It seems pretty random as our QA accidentally stumbled on it without trying, but its our highest crash right now in crashlytics albeit only 22 instances as our DAU is still relatively low, but still a decent percentage thats going to grow as our DAU does. Unfortunately, we are unable to send a minimal project. Would any other info help, like the entire stack trace log output from crashlytics?

[MorrisRH]

I've not been able to reproduce this but going by the call stack you provided it does seem to be a race condition between Unity's main thread and render thread so I've added some extra protection which I hope will prevent it from occurring. This will make it into the next release, version 3.3.0.

[Chris-RH]

AVPro Video version 3.3.0 has been released. Please let us know if it has not fixed your issue.

[SamJenkinsAim]

Thank you for the update. We will get this in and plan on releasing a new update in a few weeks. If we still see this with the new v3.3.0, I can re-open this ticket to let you know
