Description
I started notice such crashes in our users crash reports since we migrated effects from Qt5Compat GraphicalEffects to MultiEffect.
It doesn't reproduces for us locally, so I have no any simple reproducer for this at the moment.
There are crashes both on Windows and macOS.

Crashed in QQuickMultiEffectPrivate::updateEffectShaders() on m_shaderEffect->setFragmentShader(fs)
Pay attention that m_shaderEffect is nullptr at the moment.
