There is actually a problem that me and some others have been experiencing with crash right after reloading the level. This occur after generating the AI grid.

This won't help you solve your problem but maybe understand him, so look here ;

Those are threads (today's fresh) about the Ai grid problem. Maybe for you the problem is located elsewhere but i recommand taking a peek just in case your problem is somewhat the same.
I too believed at first that the "protected memory" and the "MalePlayer000 don't have alignment" were the cause of the crashs but after "experiencing" a bit it appear those reloading crashes only occurs if the AI grid is generated.

Try reloading a new level without the AI grid, if it still crash look forward to uncheck "read only" in the properties of the Data folder in your Divinity Original Sin folder.
Hope this will help.
