Zwift blacks out screen and unresponsive

I’m not sure what troubleshooting I can do, but this has been happing ever more frequently lately. It started during the MAAP rides where I would be 2-3km from the finish, my monitor would black out entirely (audio is continuing to play), then zwift becomes unresponsive. The app is open, and everything at that point is stuck–power target for the interval, audio, etc.

The actual display is whited out and nonresponsive. I cannot close the app by clicking “X” and must ALT CTRL Delete force-shutdown.

Most recently, I was on about lap 21 of 25 on the volcano circuit and it crashed :frowning: anyone have a similar issue and can offer help?
