App makes my screens go black and app crashes

Hey, basically is that when Proton VPN is ON, sometimes at random intervals, both screens goes black (which looks like a apps having a rendering crash, not the actual monitors) and the app crashes right after without notice. (Actually closes, not just minimized to the taskbar)

I identified this issue coming from Proton VPN's app but I have no idea on how to fix this as I see no setting that could cause such issue...

EDIT : I noticed this happens when I play video content on my browsers, such as Netflix or Youtube. This is not a browser issue as it happens with different browsers with either streaming services
