The cutscene freeze is something seen normally with Intel Video cards at present , try lowering all gfx settings to low and retry the cinematic.
The crash on mouse over is also a fairly new thing seen and also appears to be intel video cards , example this thread and this thread
I would then be making the assumption you likely have a intel video card
Make sure all your drivers are up to date. If they are it may be worth trying to reinstall the graphics card driver.
Depending on what you are willing to spend, if you do a lot of gaming it may be worth getting a new graphics card. I have never had any issues with the Nvidia cards and installing one of those solved all sorts of issues for me on various games etc.
If not and the reinstall doesn't work it may be worth trying to contact someone via intel support and seeing if they have a fix you can download for these sorts of problems.
Also worth trying is installing another game that has cutscenes etc and seeing if you have the same problems. Could just be that your card isn't good enough anymore or is faulty.
Sorry cant guide you to any outright fixes but these steps might help you sort it or at least rule out some possible problems 🙂
