I'll try again, but this time swap to gpu and back to cpu before I do anything, just in case the visible property is not representing the actual value.

Hi Sergey, it's still crashing. Please see the attached video demonstration, and I've also attached new log files.

Please could I ask that you don't remove the ability to change the image…

@Sergey that's great thanks, you're a legend Sir. For anyone facing the same issue with their addons, here's a solution which prevents the image being updated until the compositor has finished…

@Sergey The issue doesn't appear to be related to updating the compositor during playback, as that works fine providing render.render isn't used to force the playhead to wait for the compositor to…

Access violation crash when updating image datablock during playback and using render.render to force playhead to wait for compositor to complete.

I don't think it's due to any changes in the Nvidia drivers, because the gpu driver on my windows 10 machine hasn't been updated, and the crash wasn't happening with it previously when I reported:…
