ASUS TUF A15 - Games couldn't Open Error '0xc00007b'

I've installed games in my new laptop ASUS TUF A15 but some of the games couldn't perform and appeared an Error code 0xc00007b. However, these games in my previous laptop are still work perfectly. I tried few ways like Run as Administration and dll., but
it doesn't work.

Thanks so much for this! Was facing a similar issue also with my new asus tuf a15 - download mbps was about 1/4 of speed tests on other devices. Gaming was a struggle. I did all three of the steps above + the power management suggested previously. Fixed!
