I can’t open the sims anymore?

LocalCatStealer​  A dxdiag is a system report.  It lists hardware, some peripherals, system drivers, that sort of thing.  It also lists the ten most recent Windows errors, which includes application crashes.  In your case, these errors are saying Sims 4 crashed due to an issue with the Intel graphics driver.

However, the game shouldn't be using this driver or the integrated graphics chip.  Have you told it to do so?  One place you could have would be the Nvidia Control Panel; the other would be under Windows Settings > System > Display > Graphics settings.  In both cases, please check the setting for TS4_x64, and if it's set to use integrated graphics or the power-saving option, respectively, switch it back to the Nvidia option.

Please also only play while your laptop is plugged in.  Running the game on battery can cause the system to default to the iGPU even with the other settings favoring the Nvidia chip.
