The issue

In my game, I do PrepareCapture as part of the loading. Then user have an option to start the game, which also calls StartCapture, or to abort, which unloads the scene in which the CaptureFromCamera exists (Then StopCapture called form CaptureBase's OnDestroy).
When StopCapture is called, I get the following errors (attached in the Log output section below), which also sometimes lead to a crash.
I tried calling UnprepareCapture, and/or CancelCapture, but still get the same errors.
Adding to UnprepareCapture
_handle = -1;
seem to fix the issue. But i'm not sure which side effects this may have, and if there is something else wrong I'm doing which leads to this issue.

Setting the handle to -1 is going to prevent the native part of the plugin from being able to clean up and free off resources so I would advise against that.

Could you provide details of the crashes you're experiencing (crash logs, tombstones, etc.)?
