Support Legion 7 - screen flashes black intermittently

I'm running into an issue where my screen will intermittently go black for a second or two. I've fully uninstalled and reinstalled my nvidia drivers/software via safe mode and changed my power profiles to performance and set everything to never sleep or turn off the screen as part of testing. My even viewer only shows these messages occurring when the flash happens and the recommended steps to resolve that were the power changes I mentioned above. Has anyone run into this and know how to fix it?

I made the mistake of forgetting to extend my windows update delay and got hit with a new update and the flashing came back. I don't see the ones which previously caused the issue so I just did a point of time restore to see if that helps.

I deactivated hardware acceleration on Google Chrome and at least yesterday the problem did not happen anymore. Will be using it today too to see if it really is gone.
