HOW TO FIX LAPTOP BLACKOUT WHILE GAMING AND PLUGGED IN?

Good Day, everyone! I have an issue with my laptop Acer Nitro V15, when I play games and the charger is plugged in, the screen is randomly blacking out, but the laptop is still working, only the screen is black. Do you know how to fix this? I already tried all the videos on YouTube, and all the drivers are updated. I also went to the store where I bought my laptop, but they couldn't fix it. It is only happening when the laptop is charging. If you have a solution to this problem, pls email me or reply to this in the comments. Thank you so much, and God bless Y'all.
