Crash - Concurrency problems when integrated with AVPro Media Capture

    I integrated AVPro Media Capture to record a render texture with the webRTC video feed.
    The purpose is to record what a VR user is seeing in real time.

    Target platform is iOS.
    I'm getting the following error when trying to record:

    2022-07-26 14:23:36.821896-0300 MyProject[66755:5003449] -[AGXA10FamilyCommandBuffer renderCommandEncoderWithDescriptor:], line 380: error 'A command encoder is already encoding to this command buffer'
    -[AGXA10FamilyCommandBuffer renderCommandEncoderWithDescriptor:]:380: failed assertion `A command encoder is already encoding to this command buffer'
    dyld4 config: DYLD_INSERT_LIBRARIES=/Developer/usr/lib/libMainThreadChecker.dylib:/Developer/Library/PrivateFrameworks/DTDDISupport.framework/libViewDebuggerSupport.dylib

    When I don't start the WebRTC session, and try to record, the issue goes away.
    Even if I establish a WebRTC connection with no Streams, the bug is still there. I tried removing the video stream but still crashing.

    Any idea about what might be causing this? Maybe some semaphore or mutex could be added to avoid it?
