No, I have an NVIDIA GeForce GT 720M and an Intel core (they can be switched, as I already did, but it did not help), if I looked correctly in the settings in Notepad. Just in case, I checked GraphicsRules, but RenderShadowMode is already set to 2. I also changed the graphics settings inside the game: I set it to high, medium and low, but the problem remained the same.
@hjnm4mmsje2t It's possible this problem showed up the last time your laptop updated its graphics driver. The last driver available for the GT 720M is from 2019, but that doesn't mean it installed right away. In case you want to compare driver versions, this is the newest one:

Please also try switching off Advanced Rendering if it's on, or vice versa. Do so at the Main Menu, then quit to desktop before loading a save.
Other than that, I'm not sure what you can do here. It's difficult to address one-off problems like this on older hardware and an older OS for a few reasons, not the least of which is that some software has continued to receive updates while other software does not. For example, a Windows update could have broken this feature as well, with up-to-date graphics drivers compensating but not those that had already been released.
