    2021.3.17 appears to have fixed this error for us. -,looking at the release notes, this may have fixed this issue:

    'Networking: Fixed race condition between DownloadHandlerTexture and Resources.UnloadUnusedAssets, sometimes cause premature destruction of the texture. (UUM-18044)'

    For our project this issue started happening when upgrading from 2021.3.9 to 2021.3.10.
    Looking at the release notes, this 'fix' might have broke something:

    Networking: Fixed a texture leak when UnityWebRequest is used with DownloadHandlerTexture and a texture is never queried. (UUM-953)

    We are also affected by this issue, that happens on iOS and Android builds. Commenting the line where the downloaded texture is destroyed fixes the crash, but it will leave the texture in memory, so it's not really a workaround :(

    This crash also happens on Android. I hope it can be fixed soon. We refactored our codebase to reduce the chance of hitting this crash, but it can still happen after a Texture2D is destroyed.
