that is not why I asked.
if you start a new game and play without saving, does it crash or not?
if it does not crash, then it means that the savefile is incompatible to your current set of plugins.
Now the next step would be to check why the savefile becomes incompatible
if even new saves automatically become incompatible even without any changes in the plugin manager (which is the usual way that invalidates savefiles), then you have two or more plugins that are incompatible to each other.
and that is exactly why I asked for screenshots of your plugin manager, because only with a full list of all plugins, their order and their version numbers we can help you find the cause of the problem.
EDIT: sorry, didn't see that you added the screenshots to the top post.
are those screenshots in that order? It is usually better to use alt-prtscrn for screenshots and not to cut away anything, because you cut away the scroll list and that makes seeing the order of the screenshots difficult.
I think that the order of the Q plugins is the problem, but I don't know enough about them to be sure.
You should move QABS to the second place after QPlus and then try again.
