Steps to reproduce

Use Flutter 3.35.x (stable).

Run an app on Android with Impeller enabled (default).

Navigate to a widget tree that uses a Texture/VideoPlayer or otherwise triggers GPU rendering.

App crashes with above error.

Expected results

Impeller GLES should render correctly without crashing.

Actual results

App crashes immediately when Impeller tries to encode GL commands.

    Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
    If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
    Thanks for your contribution.
