Insert media while posting is not working with new wordpress update

I disabled the post thumbnail editor plugin, then everything started to work again as normal.

But for the general advise for similar kind of issue is, disable your plugins one by one and test. Then you can find the plugin which is not compatible with wordpress update. So that you can disable that plugin at lease until it is giving new update.
